How to Watch New Zealand's Streaming Online TV show from outside New Zealand

Maybe you're a citizen of the New Zealand who's moved abroad and you miss keeping up with your favorite television shows-or maybe you're just an American who is curious what TV in another country is like. 

Whatever the reason, if you've ever tried to go to a streaming TV website such as iPlayer, iTV, Hulu or Netflix and you're in a different country, you're greeted with a message telling you that due to restrictions they can't let you watch anything. Bummer! 

How does it know that? What's happening is that the website looks at your public IP address and uses it to determine your location.  Watch TV on websites which restrict IP's,ou can now watch tv series outside of the New Zealand.

The solution to this problem is to use what is called a VPN. Using our new New Zealand VPN server we can help you traveling abroad to watch their favorite TV shows.

How to Play online Poker with VPN

How to Play online Poker with VPN

federal government of the Unites States made a crackdown on many well known and really popular on-line casinos. Many gambling websites like Pokerstars, Full Tilt Poker, Absolute Poker and others suffered from that step. 

What was the reason for that action? Taxes? Money? Division of power of influence? Who knows? 

But what I know for sure is that millions of Poker players are very unhappy about that. People played poker in on-line poker rooms and they will do this independently on any blocks and restrictions.

I do not think and gambling is very good but I am sure that adult people have their right to chose play poker or not.

For those who are looking for a safe and easy way to play poker I can suggest using poker vpn. It help you to hide your IP and stay anonymous and protected on-line. You can get and access to on-line casinos that are blocked from USA IP address. 

VPN for poker is a virtual private network that is a secured tunnel between your PC, iPhone or iPad and vpn server that can be located in any country of the world. Your real IP is hidden under the poker vpn and all the traffic in this channel is encrypted so nobody can monitor your Internet activity. 

When you are under the vpn you have another IP address (the address of your vpn server). It can be European, Canadian and any other else. So in such way you can play poker in on-line casino staying in the United States.

VPN for poker is the best opportunity to stay anonymous and play poker safe and protected. This is reliable and stable connection.

Poker vpn can be created fast and easy with personal vpn provider. Special set up guides will help you to make a new poker vpn connection.

VACMAN Middleware software suite

g an abridged journey to a foreign location, Key Features_  Secure private networkMulti Screen Media VASCO's DIGIPASS technology combined with the VACMAN Middleware software suite, allowed MSM to secure its SSL/VPN solution in a very cost-effective manner. The authentication solution was seamlessly integrated into the existing back-end infrastructure using RADIUS protocol. Employees can now securely access the corporate network and its applications anywhere, anytime using DIGIPASS GO 6products. Since its launch in October 1995, the company created an impressive portfolio of programs ranging from the light-hearted to the supernatural, exploring various genres complimented by a mix of glamorous events and Bollywood blockbusters reaching more than 42 million households in India alone. Additionally, SET is also available in the United States, United Kingdom, Africa, Middle-East, Europe, Canada, Australia, New Zealand, Singapore, Nepal, Bangladesh, Maldives and Malaysia; reaching over 300 million households worldwide.STATIC PASSWORDS INADEQUATE FOR REMOTE USEIn order to allow its IT staff and telecommuters to access the corporate network and its resources, MSM implemented an in-house SSL/VPN solution. However, with increasing numbers of remote users needing to access business-critical applications, confidential documents and other sensitive information; security became a top priority. MSM wanted something more secure than traditional password/ username combinations by adding an extra security layer to ensure that only authorized staff could gain access to corporate resources through VPN.

packets as a part of VPN

Mobile IP (MIP) is one of the most popular solutions for handling IP mobility problems at OSI Network Layer. It is a standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address [23]. There are two versions of Mobile IP: Mobile IPv4 [23] and Mobile IPv6 [15], which work for IPv4 [40] and IPv6 [41] networks respectively. This chapter will first discuss the key concepts of different versions of Mobile IP and then analyse the problems faced by Mobile IP when transferring packets as a part of VPN without double tunneling. 3.1 OVERVIEW OF MIPV4 Mobile IPv4 is a protocol enhancement that allows routing of IP packets to a moving node under IPv4 networks. Only the OSI Network Layer is enhanced to handle the problems so that the upper layer softwares can be used without any modification.  The basic components of Mobile IPv4 are: (1) Mobile Node (MN): A host that changes its point of attachment from one network to another. Its IP address will change in this situation. (2) Correspondent Node (CN): A host communicating with a Mobile Node. (3) Home Agent (HA): A router on a Mobile Node's home network. It keeps a permanent IP address (Home Address) for each Mobile Node and maintains current location (Care-of Address) for the Mobile Node. It is responsible for tunneling packets to Foreign Agent when the Mobile Node is away from home, and advertising itself. (4) Foreign Agent (FA): A router on a Mobile Node's visited network which provides routing services to the Mobile Node when registered. It is responsible

layer 2 VPN

Types of Layer 2 VPN There are three main types of layer 2 VPN.  Each provides a different type of service to the customer.  This chapter describes the main types of layer 2 VPN and goes on to describe some of the solutions for implementing these types of VPN together with details of their current state of industry acceptance and deployment. 5.1.1 VPWS Overview The first type of layer 2 VPN we will look at provides point-to-point connectivity between customer sites.  This type of VPN is known as a Virtual Private Wire Service (VPWS) and the service provider network can be thought of as emulating a set of wires between the customer sites.   This is particularly useful in the case where a customer is currently using a set of ATM or Frame Relay connections between the different customer sites, as existing links between the customer and provider can be used.  The customer can keep the same layer 2 connections to the service provider, but instead of data being carried natively over an ATM or Frame Relay service, the traffic is encapsulated and routed over the provider's IP backbone   This clearly minimizes the migration cost to the customer.  It also means that this option is particularly appropriate to migrating specific existing networks – such as those based on a hub-and-spoke architecture which requires a number of branch offices to have connectivity to a single main office or data-center. The following diagram shows the point-to-point layer 2 connections between the customer sites, illustrating a section of each connection being emulated by the provider network. IP backboneCustomerSiteCustomerSiteCustomerSiteLayer 2Access CircuitsLayer 2 connections emulated bythe service provider's IP networkCopyright © 2003-2004 Data Connection Limited.  All Rights Reserved. Page 13 http://www.dataconnection.com5.1.2 VPLS Overview Another type of layer 2 VPN is a Virtual Private LAN Service (VPLS).  In this type of VPN, the Ethernet LAN at each customer site is extended as far as the edge of the provider network.  The provider network then emulates the function of a LAN switch or bridge to connect all of the customer LANs to create a single bridged (Ethernet) LAN.   One of the main differences between a VPWS and the VPLS described above is that the VPWS only provides a point-to-point service, whereas the VPLS provides a point-tomultipoint service.  This also means that the requirements on the CE devices are quite different.  In a VPWS, layer 2 switching must be carried out by the CE routers, which have to choose which Virtual Wire to use to send data to another customer site.  In comparison, the CE routers in a VPLS simply send all traffic destined for other sites to the PE router. SP network acts as a virtual LAN bridgeSP networkCustomerSiteCustomerSiteCustomerSite5.1.3 IPLS Overview In many networks, only IP traffic needs to be exchanged between customer sites, and the customer edge device is an IP router, instead of a layer 2 switch.  If this is the case, then it is possible to use a third type of layer 2 VPN – an IPLS (which stands for IP-only LAN-like Service, IP over LAN Service or IP LAN Service, depending on which Internet draft you read.).  As this type of VPN only forwards IP traffic, it is easy to confuse an IPLS with a layer 3 VPN – however, as traffic is forwarded based on the layer 2 header information, the IPLS still falls into the layer 2 VPN category. 5.2 VPWS Solutions In this section, we consider four VPWS solutions.  Each gives the customer a VPWS that looks like a traditional layer 2 VPN made up by connecting the customer sites using ATM or Frame Relay leased lines.  In each case, this is done by emulating a set of pointto-point wires between the CE routers.  The main differences between the solutions lie in the amount of configuration required by the service provider, and the types of tunnels used through the provider network.

Romanc�<@cr�ran lang=EN-US>  Capital Cost (to the VPN user).  The VPN user may require a solution that does not involve a costly replacement of their existing hardware.  Therefore, any VPN solution offered by a service provider must not require expensive extra function to be added to the customer edge devices.  Ideally, the solution will be fully interworkable with the VPN user's existing switches and routers. •  Manageability.  The VPN user will want a solution that is simple to manage and which minimizes the migration costs. The configuration of the VPN solution should not be so complex that the network management personnel require extensive training.  Neither should the solution require a significant overhaul of the VPN user's existing network architecture.  Equally, the ongoing day-to-day management should not be too onerous – for example, it should be easy to add new sites to the VPN.

set-top box vpn

devices to the network. In 1992 and again in 1996, Congress passed laws to ensure the commercial availability of third-party cable devices,107 and the FCC has sought to implement Congress' directive, if somewhat unevenly, sometimes half-heartedly, and often incompetently.108As a result, the set-top box is not subject to competition or innovation (many boxes consist of very old technology109), and cable operators rent boxes to users at very high monthly prices. As a Wired author noted, "The set-top box vpn has proven to be a closed and well-guarded fortress against a world of clouds and openness," and the incumbents "work strenuously to keep it that way."110The FCC admits its policies have failed. In late 2009, the FCC concluded that "set-top box competition has not emerged, limiting innovation."111 In 2008, there were only 14 set-top boxes on the market, including those leased by cable TV distributors; by contrast, there are 900 mobile phone and handheld devices on the market.112 The Consumer Electronics Association, which represents thousands of companies, has fought for years to open up the set-top box market. As their vice president recently concluded, "It's been a long slog. … Cable operators have been loath to give up control."113Device-makers can, however, attach boxes to the  Internet connection through, for example, an ethernet jack.114 This has resulted in devices like Apple TV, Roku, Vudu and Boxee's announced device — as well as the ability to connect televisions, gaming consoles, computers and BluRay players. But in a move that drastically reduces the consumer-friendliness of these boxes, the cable industry forbids outside boxes from integrating cable TV offerings within the same interface used for navigating online TV.115 For example, Boxee's popularity rests on it being a user-friendly interface that displays, in one place, TV content from users' hard drives and multiple sites across the Internet.116 As a result of this restriction, users cannot easily "change channels" among online and cable TV programs.117 While public TV distributors in Europe have moved to incorporate online and cable TV into one interface,118 the cable industry lobbying association has recently argued that

revenue sharing costs.  Using the CineMatch software, Netflix can guide members to rent older movies or those released by independent studios, increasing their bottom line and improving customer service by guiding members toward movies that are more likely to be in-stock.   This leads to the argument that perhaps Netflix should focus more on the niche market of older, foreign, and independent movies and leave the high demand new releases to Blockbuster. Operational Costs: Distribution Centers versus Stores  Netflix's distribution system has cost advantages (Table 2).  As opposed to the over 8000 retail locations for Blockbuster, Netflix has just 20 distribution centers across the nation, with plans to open one or two more each month in 20036 based on the movie market in that region.  According to Reed Hastings, founder and CEO, the company is able to keep overhead low as the small distribution Netflix Pakistan VPN proxy center facilities have low rent and require a low number of employees to operate.7   Each is staffed by approximately 12 employees and each processes about 15,000 DVDs per day9.  As distribution centers move into areas, members in close proximity can expect to see turnaround drop from about one week to just two days, increasing the number of DVDs they can possibly view in a month.   Netflix has experienced a popularity surge in cities with new local distribution centers.  The drawback, however, is that faster turnover and higher viewing rates result in more postage fees for Netflix, creating a tradeoff between increased customer satisfaction and increased costs.  Also, a typical revenue sharing agreement requires payouts for each rental of a new release during the first year, so a higher rental rate will result in more rentals of a film and therein more revenue sharing costs.

How many incoming VPN

admitted into theVPN

For the purpose of dynamic bandwidth control, a VPG-based VPN can be compared to anATM network in which the link size can be varied. Therefore, controllers in the customerdomain operate on two views of the network (Figure 4). The view on the left side of Figure 4shows a network of end-to-end VPs which connect a set of CPNs. The view on the right showsa VPG network, which connects the same set of CPNs. The relationship between VPs andVPGs defines the mapping between both views.The VP admission controller, which participates in call setup and release in the enterprise network, operates on the left view. The controller decides whether a call can be admitted into theVPN, based on the VP capacity, its current utilization and the admission control policy. TheVP admission controller always ensures that enough capacity is available, such that cell-levelQOS can be guaranteed for all calls that are accepted. The controller runs on the time scale ofthe call arrival and departure rates (seconds or below). There can be one VP admission controller per VP, or one for a set of VPs. The VPG controller operates on both views. Depending onthe state of the VPs (in particular, traffic statistics and VP size) and the control objectives, itdynamically changes the amount of VPG bandwidth allocated to associated VPs. This controller enables customers to exploit variations in utilization among VPs that traverse the sameVPG, allowing bandwidth between VPs of different source-destination pairs to be shared without interacting with the provider. In order to guarantee QOS, the sum of the VP capacities mustbe less than or equal to the capacity of the VPG link. The controller runs on a time-scale ofseconds to minutes. The VPN controller operates on the right view. It is the only controllerwhich interacts with the provider, and it runs on the slowest time scale of all the controllers(minutes or above). The VPN controller dynamically negotiates the bandwidth of the VPGlinks with the provider, based on traffic statistics and control objectives (e.g., minimizing theVPN cost), while observing the customer's QOS requirements.

VPN IP address of your own internet provider

Several information resources of the Erasmus MC Medical Library and of the Erasmus University Library are protected, that means, have restricted access. The provider of the information keeps in check if the licence applies to the code (IP address) that is sent by the information asking computer.IP addressOn logging in to a network, the computer receives an address code (IP address) to recognize that computer from outside that network. An IP address consists of four groups of maximally three digits. For computers that are logged onto the network of the Erasmus MC, IP addresses always start with 156.83, for the EUR that is 130,115. But from home you have the IP address of your own internet provider, e.g. 87.208.xxx.xxx(Tele2). With that you will not have access to the shielded information.Shielded informationMany bibliographic databases only have licenced access. That applies to EMbase.com, PsycINFO via OvidSP, Web-of-Knowledge/Web-of-Science, Journal Citation Reports (Impact Factors), Cinahl. Many journals have access by subscription (Elsevier Science Direct, Wiley, Springer), just like the electronic books.PubMed is freely accessible, but linking to shielded journal articles, requires special access. That also applies to the MedLib Catalogue (OPAC): freely accessible, but linking to the e-books only is possible in shielded surround. There also are freely accessible journals (often free for a restricted periode, e.g. forinformation older that one year. Of course, employees and students of Erasmus MC and EUR from their working places and study rooms have direct access to the shielded information: those computers are default logged onto the network of Erasmus MC or EUR.Within the buildings of Erasmus MC there are two distinct wireless networks:1. the shielded one (IP address 156.83.*.*);2. the free, not shielded 'Hotspot' (IP address 70.172.*.*?).Using the 'Hotspot' is just like working from home (or elsewere): no access to shielded information.

Internet technology VPN

Internet technology has been the fastest growing areaof information technology in recent years (Keeney1999). Its rapid development, implementation and useby the individual and organizations have created bothopportunities and challenges for the management of thistechnology. The rapidly emerging Internet technologiesare in¯ uencing not just the management of product andservices but also the rethinking of business processes,®rm structure and even industry boundaries. EŒectiveuse of this technology is increasingly considered as amajor determinant of competitive advantage, productivity, and even individual competency.Internet usage by the individual is a pivotal conceptthat in¯ uences our understanding of the social andeconomic impacts of information technology. MISresearchers have proposed usage as a central conceptin taxonomies of success (DeLone and McLean 1992,Doll and Torkzadeh, 1998). Usage is also proposed as aMIS success measure in several frameworks for research(Ein-Dor and Segev 1978, Hamilton and Chervany1981, Ives et al. 1980). Jonscher (1983) suggests thatimprovements in the way that information technology is

Network Access Control VPN

Network Access Control

In addition to NIDS, access control, generally through the use of a firewall, should be performed before and after the VPN

device. When done on the interior of a VPN device as traffic heads toward the campus, the access control can ensure only

that the proper address ranges and protocols are allowed. As was mentioned earlier, most policies for VPN access tend to

allow the remote users to use almost any protocol they could on the local LAN. As such, it may be easier to define the

protocols you don't want your remote-user communities to be able to access, rather than define the ones that you do want

to allow.

In larger deployments, it is helpful to segment the various types of VPNs off of discrete access control points of the network.

This can be done through providing a dedicated firewall interface for each VPN type, as was done in the large VPN design.

This setup allows different levels of trust for different VPN applications. For example, an organization might decide it trusts

site-to-site VPNs a little more than remote-access VPNs. This better trust is a result of the fact that with site-to-site you know

the IP address of the remote peer and are potentially using digital certificates, whereas with remote-access VPNs you generally

do not know the address of your remote peer and are relying on group preshared keys combined with secondary

authentication to allow your users into the network. When deployed in this manner, VPN traffic can be filtered differently

based on what interface it arrives on at the access-control device.

Filtering outbound from the VPN device (toward the public network) is also important. This filtering can help ensure that

the VPN devices see only IPSec traffic coming into and out of their public interfaces. This filtering can generally be done on

a router with a standard ACL instead of a firewall, freeing the firewall to sit behind the VPN device as was specified earlier.

This setup is in contrast to many deployments today that place the firewall in front of the VPN device. When placed in front,

no visibility into the specific types of user traffic is possible because the traffic is still encrypted. Most of the benefits thatCisco Systems

 

stateful firewalls could provide in front of a VPN device are lost regardless, because IPSec traffic cannot be intelligently

filtered by most firewalls. The administrator would need to open a hole through the firewall to allow the traffic (that is, UDP

500 for IKE and IP 50 for ESP) and at that point, it is behaving in much the same way as a standard packet filter on a router.

Filtering inbound on the VPN device itself is recommended to allow only IKE and ESP. If the NAT transparency mechanism

is enabled, you should allow only the specific UDP or TCP port to the VPN device.

Often this access-control function can exist on the same hardware platform as the IPSec function. It can if your VPN device

also has a stateful firewall, or when a remote user connects using a laptop that has both VPN client software and a personal

firewall.

adaptiveVPN, modifications

IPSec client modifications. To support adaptiveVPN, modifications have been made to both theLucent IKE module and the IPSec NDIS driver. TheLucent IKE module has been modified so that it cannegotiate IKE sessions with two or more externalendpoints at the same time. (To support adaptiveVPN, the ability to negotiate with two endpoints issufficient.) The modified Lucent IKE module is capable of pushing SA information and keys for multipleIPSec tunnels to the IPSec NDIS driver. The SA database has been modified so that it can maintain information about multiple IPSec tunnels, including thehost subnet IP addresses and TCP port numbers forwhich packets should be sent through that tunnel. Inaddition, the IPSec engine has been modified so that,based on the SA database information, it can addthe appropriate (outer) IP headers and de-multiplexthe packet through the appropriate tunnel. Let usconsider an example to illustrate the effect of thesemodifications. Figure 10 shows an example of a networkarchitecture. The client with physical IP address135.180.144.174 has two tunnels, one to an enterprise gateway at IP address 135.180.144.254 andthe other to a network VPN gateway (or an IPSS thatsupports VPN) at IP address 135.180.244.150. Thelocal presence IP addresses of the two tunnels are192.168.5.10 and 192.168.1.10, respectively. Thehosts behind the enterprise tunnel are in the subnet192.168.5.0/24 and the hosts behind the networktunnel are in subnets 192.168.1.0/24 and 192.168.3.0/24. With the modifications we have made, theLucent IKE module is able to negotiate IPSec parameters for both the tunnels with the two VPN gatewaysand to keep both tunnels active at the same time. TheSA database keeps information about both the tunnelsto enable the modified IPSec engine to de-multiplexpackets through the tunnels; packets destined to subnet 192.168.5.0/24 are sent through the enterprisetunnel, and packets destined to subnets 192.168.1.0/24 and 192.168.3.0/24 are sent through the networktunnel. Based on local presence IP address information and information about the hosts behind eachof the tunnels, the Lucent IKE process modifies the routing table. The modified routing table is shown inFigure 11. Let us examine how IPSec processing willtake place, based on the routing table shown in thefigure.

Mobile IP and IPSEC

In the first solution, shown in Figure 5, we assume that the mobile host has a fixed home IP address and home agent assignment. The home agent is either in the home access provider's network or at the corporate network that the mobile user wishes to access. In the latter case, a firewall exists and we assume that the access gateway/firewall at the corporate network supports home agent functionality. Mobile IP client software is assumed to be running in the mobile host, while foreign agent software is running at the IWF. Both the home and foreign agents support bidirectional tunneling and enhanced mobile IP mobility agent's functionality as specified by Zao et al.( n15) IPSEC is supported at the firewall/gateway (if one exists) or the home agent (HA). We assume there exists some prior arrangement between the home/ visiting access provider and the corporate network to obtain the shared key information for mutual authentication of the foreign agent and the firewall.Otherwise, a key management protocol such as the IETF's Internet security association and key management protocol (ISAKMP)( n16) is required.

In this solution (shown in Figure 6), we assume that the mobile host is using the foreign agent address as the "care of" address. The foreign agent (FA) indicates via the agent advertisement to the mobile host that it can support IPSEC. For the rest of the description, we assume that a firewall (FW) exists. During the registration procedure, the mobile host sets the "FA/FW IPSEC required" bit in its mobile IP registration request message and sends it to the FA (step 1 in Figure 6). The FA authenticates the message and determines the associated FW (potentially with the help of an authentication server) based on the destination address of the registration request, which is the HA's address (step 2). The FA then builds a secure tunnel between itself and the FW and relays the registration request to the FW (step 3).

Upon receiving the encrypted registration request, the FW decrypts it (step 4) and relays it to the specified HA (step 5). It is assumed that the header of the secured tunnel carries sufficient information for the FW to authenticate the FA. It is also assumed that the key used to decrypt the registration request is unique to each FA. The HA authenticates the mobile host upon receiving the request. If the service request is granted, a registration reply will be sent to the mobile host via the FW (step 6). Next, the FW initiates accounting for the session (step 7). The FW then encrypts and sends the registration reply to the associated FA (step 8). The FA decrypts the registration reply and initiates a local accounting transaction (step 9) before relaying it to the mobile host (step 10).

Once the registration process is over, a mobile IP and IPSEC tunnel is established between the FA and the FW. When data packets from the registered mobile host arrive at the FA, it encrypts them, adds the encapsulating security protocol (ESP) header, and sends them through the secured tunnel to the FW. The FW decrypts the packets and delivers them to the corresponding node (CN) inside the corporate network. All packets sent by the CN to the mobile host will be captured by the HA, encapsulated, and sent to the FW. The FW encrypts them, adds ESP headers, and relays them to the FA. The FA decrypts the packets and delivers them to the mobile host. If end-to-end security is desired, the link between the FA and the mobile host must also be encrypted.

When the mobile host moves from one FA to another, it reregisters with the HA. The hand-off latency is a function of how quickly the mobile host can detect an agent advertisement from the new FA. Of course, link-layer hand-off messages could be used to trigger an agent advertisement from the new FA. Only two messages need to be exchanged between the mobile host and the HA for reregistration, provided new security associations need not be negotiated. Potentially, a minimum of 8 and a maximum of 13 messages are needed for IPSEC operations if we use ISAKMP as the security association and key management protocol. Two local messages may be required if the HA needs to access a local authentication server to verify the mobile's identity. Two more local messages are required at both the FW and the FA for accounting purposes.During handoffs, the tunnel between the new FA and the FW needs to be built; thus, potentially, some data packets may be lost. This loss can be minimized by requiring the mobile and the FAs to support the previous FA notification extension. Upon being notified by the mobile host of the identity of the old FA, the new FA sends a message to the old FA. The old FA then forwards the buffered data to the new FA. The Global System for Mobile Communications (GSM) General Packet Radio Service (GPRS)( n17) specification provides such a packet-forwarding feature.

The advantage of using alternative 1 is that the required software can be easily produced by modifying available off-the-shelf mobile IP and IPSEC codes. The disadvantages of using alternative 1 are as follows:

• Mobile IP mandates mutual authentication between the mobile host and the HA. Currently, it is assumed that security keys and security index parameters are manually configured, since there is no standardized key management scheme for mobile IP at this time.
• There must be a prior arrangement between the home/visiting access provider and the corporate network to obtain the shared secret keys. More than one set of keys may be required for each corporation. If only one set of keys is used, a centralized database must be provided so that all FAs of the serving carrier can access that information.
• The hand-off latency is larger, since the registration path spans across multiple domains.
• Since mobile IP does not address any accounting issues, an accounting mechanism must be furnished via some other means. One may use either cellular digital packet data (CDPD) accounting or the IETF's RADIUS accounting. Typically, it is more cost effective to reuse an existing accounting system. With CDPD accounting, the users look more like traditional wireless subscribers. Otherwise, RADIUS accounting can be used, since it is simple, cheap, and already available in most of the ISP networks.
• Both the FA and the HA need to have publicly routable addresses.
• There is no dynamic HA feature.
• To support private addresses for the mobile host's home address, the mobile host and the HA need to perform double encapsulation. The tunnel between the FA and the HA needs a tunnel identifier to distinguish between mobile hosts that have the same private address.

One drawback of alternative 1 is that the hand-off latency is high. A possible way of reducing it is to implement the FA functionality at the PDSN rather than at the IWF. Mobility between different IWFs can then be managed via wireless access link-layer protocols. In some larger wireless access networks, multiple PDSNs may be available. These multiple PDSNs can be arranged in a hierarchical manner so that a mobile host's movement from one PDSN to another will not always result in a mobile IP reregistration message. This idea is explored in alternative 2, described in the next section.

VPN server

Dưới đây là mô tả sơ lược các thành phần của một kết nối mạng riêng ảo.

▪ Máy chủ mạng riêng ảo (VPN server): Là máy tính chấp nhận các kết nối từ các máy khách mạng riêng ảo. Một máy chủ mạng riêng ảo có thể cung cấp kết nối mạng riêng ảo truy cập từ xa hoặc kết nối mạng riêng ảo cổng tới cổng.

▪ Máy khách mạng riêng ảo (VPN client): là máy tính khởi xướng (initiate) kết nối mạng riêng ảo tới một máy chủ mạng riêng ảo. Một máy khách mạng riêng ảo có thể là một một máy tính riêng lẻ có được một kết nối mạng riêng ảo truy cập từ xa hoặc một bộ định tuyến có được một kết nối mạng riêng ảo giữa hai bộ định tuyến. Các máy tính sử dụng Windows NT 4.0, Windows 2000, Windows 9x có thể tạo các kết nối mạng riêng ảo truy cập từ xa tới một máy chủ mạng riêng ảo sử dụng Windows 2000. Windows 2000 Server và Windows NT Server 4.0 chạy dịch vụ định tuyến và truy cập từ xa (Routing and Remote Access Service) có thể tạo các kết nối mạng riêng ảo giữa hai bộ định tuyến tới một máy chủ mạng riêng ảo sử dụng Windows 2000. Các máy khách mạng riêng ảo cũng có thể là các máy khách phi Microsoft khác sử dụng giao thức đường hầm giữa hai điểm (point-to-point tunneling protocol) hoặc giao thức đường hầm lớp hai (layer two tunneling protocol) trên nền IPSec.

▪ Đường hầm: là phần của kết nối, nơi mà dữ liệu được đóng gói.

▪ Kết nối mạng riêng ảo: là phần của kết nối, nơi mà dữ liệu được mã hóa. Trong các kết nối mạng riêng ảo an toàn, dữ liệu được đóng gói và mã hóa suốt theo cùng một phần của kết nối.

Ghi chú: Có thể tạo ra một đường hầm và gửi dữ liệu qua đường hầm đó mà không phải mã hóa. Nhưng đó không được gọi là một kết nối mạng riêng ảo an toàn, bởi vì dữ liệu riêng tư được gửi qua một mạng công cộng dưới dạng không được mã hóa và có thể dễ dàng đọc được.

▪ Các giao thức đường hầm (tunneling protocol): Là các tiêu chuẩn thông tin liên lạc (communication) sử dụng để quản lý các đường hầm và đóng gói dữ liệu riêng tư. (Dữ liệu qua hầm cũng phải được mã hóa để có thể được coi là một kết nối mạng riêng ảo) Windows 2000 gồm có cả giao thức PPTP và L2TP.

▪ Dữ liệu qua hầm (tunneled data): Là dữ liệu thường được gửi thông qua một liên kết riêng giữa hai điểm.

▪ Mạng quá cảnh (transit network): Là mạng công cộng hoặc mạng chia sẻ mà các dữ liệu đóng gói và mã hóa đi qua nó. Với Windows 2000, mạng quá cảnh luôn là một mạng IP. Mạng quá cảnh có thể là mạng Internet hoặc là một mạng IP nội bộ riêng (private IP-base intranet).
