A detailed explanation of each of the following five items appears in the Firewall section
below: Packet Filter, MAC Address Filter, Intrusion detection, Block WAN PING and
URL Filter.
5.3.4.1 Packet Filter
Packet filtering enables you to configure your router to block specified internal/external
users (IP address) from Internet access, or you can disable specific service requests (Port
number) to /from Internet. This configuration program allows you to set up to 6 different filter
rules for different users based on their IP addresses or their network Port number. The
relationship among all filters is "or" operation, which means that the router checks these
different filter rules one by one, starting from the first rule. As long as one of the rules is
satisfied, the specified action will be taken.
