filter packets belong to one type. For example, two rules filter packets with
two destination IP addresses, they are the same type. But a rule filtering
source IP address does not belong to the same type.
The count of rule types is not unlimited. Turn on some special switch
functions may decrease the count. If no free type is available, the system
will show warning message and the rule will not be set.

The Filter Rule page provides options for rule modes, one is MAC rule and
the other is IP rule. In MAC rule, users can set MAC address, VLAN ID and
COS value. If you did not enter the MAC address in the blank box, it means
the rule don’t care the MAC value. In IP rule setup, you can enter any of
the 5 types: source IP, destination IP, protocol, source application port
and destination application port. The protocol filed offers TCP, UDP, ICMP
and Any for selection. 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.
