Wireless-N Gigabit Security Router with VPN
Single Port Forwarding
This is one of the NAPT (Network Address Port Translation) feature. Use the Single Port Forwarding screen when you want to open specific services (that use single port). This allows users on the Internet to access this server by using the WAN port address and the matched external port number. When users send these types of request to your WAN port IP address via the Internet, the NAT Router will forward those requests to the appropriate servers on your LAN.
Application Name. Enter the name of the application you wish to configure.
External Port. This is the port number used by the service or Internet application. Internet users must connect using this port number. Check with the software documentation of the Internet application for more information.
Internal Port. This is the port number used by the Router when forwarding Internet traffic to the PC or server on your LAN and is usually the same as the External Port number. If it is different, the Router performs a Port Translation, so that the port number used by Internet users is different from the port number used by the server or Internet application.
For example, you could configure your Web Server to accept connections on both port 80 (standard) and port 8080. Then, enable Port Forwarding, set the External Port to 80 and the Internal Port to 8080. Now, any traffic from the Internet to your Web server will be using port 8080, even though the Internet users used the standard port, 80. (Users on the local LAN can and should connect to your Web Server using the standard port 80.)
Protocol. Select the protocol used for this application, TCP and/or UDP.
IP Address. For each application, enter the IP address of the PC running the specific server application.
Enabled. Select Enabled to enable port forwarding for the relevant server application.
