To allow access from a single IP address on the Internet, select Only This 
Computer. Enter the IP address that allows access.

Range. Enter a beginning and ending IP address to define the allowed range.

Specify the port number for accessing the web management interface.

Normal web browser access uses the standard HTTP service port 80. For greater 
security, enter a custom port number for the remote web management interface. Choose 
a number between 1024 and 65535, but do not use the number of any common service 
port. The default is 8080, which is a common alternate for HTTP.

Click Apply to have your changes take effect.

When accessing your router from the Internet, type your router’s WAN IP address into 
your browser’s address or location field followed by a colon (:) and the custom port 
number. For example, if your external address is 134.177.0.123 and you use port number 
8080, enter http://134.177.0.123:8080 in your browser.

For added security, the router can be set up to share only approved USB devices. See 

57 for the procedure.

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 
to access the network and connect to other devices as needed. UPnP devices can 
automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer 
connections, or real-time communications such as instant messaging 
or remote assistance (a feature in Windows XP), you should enable 
UPnP.
