Custom IPv6 Firewall Rules tab
This tab provides the ability to manually add custom entries to the IP tables using the ip6tables command
syntax. The custom rules are executed whenever the status of a network interface changes. You can use
custom rules either exclusively or in addition to built-in rules.
The Custom Firewall rules page also shows the iptables that are currently in effect for both built-in and
custom rules. It also displays how many times each rule has been matched, which can be useful for
troubleshooting. Scroll through the page to view the iptables for Packet Filter, Packet Mangle, and
Untracked Rules. NAT rules are not applicable to this page.
