Configuring LAN (Local Network) Groups
You can create LAN groups, which are groups of endpoints that are identified by
their IP address. After creating a group, you can then configure actions, such as
blocked keywords in a firewall rule, that apply to the group.
(See Configuring URL Blocking, page 86.)
Adding a New LAN Group
To create a LAN Group:
STEP 1 Choose Firewall > Advanced Settings > LAN (Local Network) Groups.
STEP 2 Click Add.
STEP 3 Enter the group name; spaces and quotes are not supported. Click Save.
STEP 4 If the group consists of a single IP address, choose Single Address and enter the
address in the Start IP Address field. If the group consists of a range of IP
addresses, choose Address Range and enter the addresses in the Finish IP
Address fields.
STEP 5 Click Save.
