Packet Filter
Packet ltering enables you to congure your router to block specic internal / external users (IP

This function is only available when Firewall is enabled and one of these four security levels is
chosen (All blocked, High, Medium and Low). The predened port lter rules in the Packet Filter
must modify according to the level of Firewall, which is selected. See Table1: Predened Port Filter
