Specify the port number for accessing the 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 from 1024 to 65535, but do not use the number of any common service port. 
The default is 8080, which is a common alternate for HTTP.

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 
in your browser.
Universal Plug and Play
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.
