Firewall Rule
The firewall rule function enables users to set up the firewall. The WLAN Router provides
basic firewall functions, by filtering all the packets that enter the WLAN Router using a set of
rules. The rules are listed in sequential order--the lower the rule number, the higher the priority
the rule has.
