Configure custom firewall rules

For Primary Responder devices, custom firewall rules allow scripts and iptables commands to be run. These commands are run whenever system configuration changes occur that might cause changes to the firewall.

You can set variables and other common shell scripting options, but you cannot access any commands in the normal PATH (/sbin/, /bin/, etc), such as grep, awk, and sed.

To configure custom firewall rules:
