Advanced Port Filtering Page

This page allows you to define port filters to prevent all devices from sending outgoing
TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and
ending port range, you can determine what TCP/UDP traffic is allowed out to the WAN
on a per-port basis.
Note: The specified port ranges are blocked for ALL PCs, and this setting is not IP
address or MAC address specific. For example, to block all PCs on the private LAN from
accessing HTTP sites (or "web surfing"), set the "Start Port" to 80, "End Port" to 80,
"Protocol" to TCP, select Enabled, and then click Apply.
