Click Firewall > Access Control > ACL Rules.
The ACL Rules window opens. The firewall rules appear in the ACL Control List
(ACL) table. The table includes all firewall rules for controlling traffic from a
particular zone to a particular destination.
The firewall rules are sorted by the priority. You can reorder the custom firewall
rules by the priority. You can move a rule up, move a rule down, or move it to a
specified location in the list.
• To move the rule up one position, click the Move up icon.
• To move the rule down one position, click the Move down icon.
• To move the rule to a specific location, click the Move icon and enter the
target index number to move the selected rule to.
For example: A target index of 2 moves the rule to position 2 and moves the
other rules down to position 3 in the list.
NOTE: You cannot reorder the default firewall rules and VPN firewall rules.
The custom firewall rules cannot be moved lower than the default firewall
rules and VPN firewall rules.
To view the list of firewall rules that belong to the same group, choose the source
and destination from the From Zone and To Zone drop-down lists and click Apply.
Only the rules for the specified zones appear.
For example: If you choose WAN from the From Zone drop-down list and choose
LAN from the To Zone drop-down list, only the firewall rules from WAN to LAN
appear.
You can perform other tasks for firewall rules:
