Adding zones

The new zone does not appear in the policy grid until you add an interface to it, see
“To add an interface to a zone” below, and add a firewall address for it (see “Adding
addresses” on page 197).
To add a zone
1Go to System > Network > Zone.
2Select New.
3Type a name for the zone.
The name can contain numbers (0-9), uppercase and lowercase letters (A-Z, a-z), and
the special characters - and _. Other special characters and spaces are not allowed.
4Select the Block intra-zone traffic check box if you want to block traffic between
interfaces in the same zone.
5Select OK.

Deleting zones

You must remove all interfaces and VLAN subinterfaces from a zone before you can
delete the zone. You can only delete zones that have the Delete icon beside them
in the zone list.
To delete a zone
1Go to System > Network > Zone.
2Select Delete to remove a zone from the list.
3Select OK to delete the zone.
