Turn off the firewall and set <;Windows Firewall/Internet Connection Sharing (ICS)" in the “Administrative Tools"> State, otherwise routing and remote access cannot be enabled. 2. Open the “Routing and Remote Access” configuration interface in the “Administrative Tools” and select “"XX(Local)" under the “Route and Remote Access” node (if not, you need to use &ldquo Add a server & rdquo; create a), use the "Configure and start routing and remote access" under the "Operation" menu to open the installation wizard. Usually there is only one network card (otherwise, no VPN is needed), select “Customize Configuration" and continue, select “VPN Access> and ”NAT and Basic Firewall" and continue to complete the installation wizard. 3. A dialog box will pop up saying that the installation has been completed, ask if you want to start the service, and select “ is ”. 4. Optional step: Select “XX(local)”, right click to open the “Properties” dialog box, and select “Static address pool” in the “IP address assignment” under the “IP” label. ;, and add a private address range for VPN connections, such as 10.1.0.1-32. 5.

(Do not add the interface to the local, otherwise it will not be able to go up, the principle is not clear, Daren advice!) At this point, the NAT configuration has been completed. Client configuration, take Windows XP as an example: 1. Create a VPN connection: In the "Network Neighborhood" "Properties" interface, open “New Connection Wizard", select “Connect to my workplace Network & rdquo;, then select "Virtual Private Network Connection" (also VPN), just enter a name as the company name (such as VPN, it is the name of the VPN connection), if there are other dial-up connections before depending on the situation Automatically dial in, enter the server address on which the VPN service is configured, and complete the wizard. 2.
