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.
5. Click Apply to have your changes take effect.
6. 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.
USB Settings
For added security, the router can be set up to share only approved USB devices. See
Specify Approved USB Devices on page 56 for the procedure.
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.
Note: 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.
