to remove the filter set. The user should follow
the rules to make a valid filter set.
One set consists of a collection of rules. The rules having the same fields to filter
packets belong to one type. For example, two rules which filter packets with two
destination IP addresses, belong to the same type. But a rule filtering source IP address
does not belong to the same type.
Four types of rules can apply to ports at the same time. If there are more than four types,
the system automatically disables the rules.

The Filter Rule
page provides attributes of rule modes; one is for MAC rule and the other
is for IP rule. If the user did not enter a MAC address in the blank box, the rule set will
pay no attention to the MAC value. In an IP rule setup, you can enter any of the 5 types:
source IP, destination IP, protocol, source application port and destination application
port. The Action field determines if the packet should be dropped or forwarded when it
matches the rule. If a packet matches two rules with different consequences, the packet
will follow the rule which appears first in the rule list.
