It would be great to have the ability to create tabs to group firewall rules.
You could have a tab called "VLAN20" with all the VLAN20 rules, and so on.
It would be much appreciate !
WatchGuard System Manager and the Fireware WebUI both support policy tagging, which can be used to filter rules (such as based on a VLAN, if that's how you wish to sort them.)
