Peanut shells and Windows 2003 single card using peanut shell to achieve VPN graphics and text tutorial 1th/3 Page _ Server

First, the question of the proposed
In the unit has a private address for the 192.168.0.0 network, the computer is through ADSL sharing access to the Internet, a computer in the home also through ADSL access to the Internet, now want to safely at home at any time to visit the unit 192.168.0.2 this machine, many ways to achieve, the most secure is through Vpn.
Second, what is a VPN
In this case, it is now the unit 192.168.0.2 the VPN service on this machine, at home through the VPN Client Access unit This machine, establish the connection, these two machines communicate like in the local area network, such as: to 192.168.1.10 this computer to download 192.168.0.2 This machine's text (assuming that the FTP service is set up), you can type it directly in the browser: ftp://192.168.0.2 download the file. While communicating over the Internet, the entire process is encrypted, like a tunnel that only two machines can pass through the Internet, which is the VPN (virtual private Networks) virtualization private network.

Iii. Ways of implementation
Make two preparations before a VPN remote connection.
The first to obtain the VPN server access to the Internet public IP address, if it is assigned static IP, it is simple, if it is dynamic IP, it must be remotely available at any time to obtain this IP address, 192.168.0.2 This machine's public network IP is actually ADSL cat access to the Internet, ISP to the automatic allocation, and is generally assigned to the dynamic IP. The second is to do a port mapping,  we can see that this example is a way to connect to the Internet via NAT in an ADSL cat, so it is necessary to make a port mapping in ADSL, because the Windows 2003 VNP service uses 1723 ports, Map port 1723 to 192.168.0.2, which has a VPN service machine. If you are using direct dialing, open the port on the firewall.

1, Landing Www.oray.net registered Oray Passport, under the Passport to apply for domain name (Oray provided free domain name registration), the activation of the domain name corresponding to the peanut shell services, download peanut shell client, in the LAN PC or server host installed peanut Shell client landing online, or in the integrated peanut shell dynamic Domain name resolution Service Router on the passport The name and password are filled in the Router DDNS module and enabled online.
2, in the corresponding computer installation set up VPN services.
Iv. Setting up VPN services
VPN is implemented in a very many ways, with a VPN-enabled router or Linux, Windows operating system, etc., in the Windows system with a dual network card to establish a VPN server is easier to implement, but to add a network card. The introduction of this aspect of the content of a lot, no longer repeat. This article describes the use of a single NIC in Windows 2003. The following is an introduction to the actual implementation process, first of all, to configure the VPN service on the 192.168.0.2 machine.
Select Start, All Programs, administrative tools, Routing and Remote Access.
The setup process,  interface completes the set of the VPN server on the single network, where it is pointed out that the single NIC must choose "Custom Configuration" in Figure 6, otherwise it will not go on.
