The Filter Rule page provides options for rule modes, one is MAC rule
(Figure 45) and the other is IP rule (Figure 46)
. If you did not enter the MAC
address in the blank box, it means the rule doesn’t care the MAC value. In
IP rule setup, you can enter any of the 5 tuples, source IP, destination IP,
protocol, source application port and destination application port. The
Action field determines if the packet should be dropped or forwarding
when it matches the rule. If a packet matches two rules with different action,
the packet will follow the rule showed first in the rule list.
