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, if you wanted to block all PCs
on the private LAN from accessing HTTP sites (or "web surfing"), you would set
the "Start Port" to 80, "End Port" to 80, "Protocol" to TCP, checkmark Enabled,
and then click
Apply.
