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.
Field Description
Start Port Enter the starting port number.
End Port Enter the ending port number.
Protocol Select TCP, UDP, or Both
Enabled Checkmark for each port that you want to activate the IP port filters.
