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.
