First, the hardware is ready to install two network cards on the routing server, join the intranet and external network two, network settings 1, in "Network Connection", the Internet connection is "Internet Connection", the connection of the internal network is named "Local connection" 2, set "Internet connection" IP, subnet mask, gateway, DNS is ISP 3, set "local connection" IP, local mask, DNS is the LAN configuration three, installation configuration ", remote access "1." Start "Menu →" Programs "→" Administrative Tools "→" Routing and Remote Access "2, configure and enable routing and remote access Enter the" Routing and Remote Access "console, click Right click on the server. Configure and enable Route and Remote Access, and then enter the Configuration Wizard Interface → Next → "Internet Connection Server" → Next → "Setting Router with Network Address Translation (NAT) Route Protocol" → Network Card connected to the external network " Internet Connection "3, Add NAT Protocol Settings Port Mapping" IP Routing "→ Right-click" General "→" New Routing Protocol "→" Network Address Translation (NAT) "Right-click" Network Address Translation (NAT) ", Add "New Interface" Select "Internet Connection" in "New Interface" Network Address Translation (NAT) "in" Network Address Translation -Internet Connection Properties "in" Common Interface Connection to Internet ", check" Convert TCP / UDP header (Recommended) "Add the start address and end address you need to provide port redirection in the" Address Pool "option table. It is to take out all the outer network fixed IP addresses that engage in port mapping. In general, we will use an IP address, so you can use "Address Pool". "Add special port", here is the core of setting port mapping, which port which port which ports to the NAT host is set here. "Public Address" refers to the fixed IP address of the external network, "Pass Port" is the port of the external network, "dedicated address" is the IP address of the machine in the LAN, "Incoming Port" is the port of the machine in the local area. Third, set the client through the gateway route to network 1. Enable DNS "forwarder" "Start" menu → "Program" → "Administrative Tools" → "DNS" Right-click Server → "Prototer" on the DNS Server "Tab → Select Enable Repector" → Enter the public network DNS address 2, set the client to fixed the intranet IP address, the gateway address is the IP address of the routing server, (such as the client installed Proxy client program must be uninstalled ), Do not enable proxy servers in IE.
