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. 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.
