Configure custom firewall rules

Custom firewall rules consist of a script of shell commands that can be used to install firewall rules,
ipsets, and other system configuration. These commands are run whenever system configuration
changes occur that might cause changes to the firewall.
To configure custom firewall rules:

WebUI
1. Log into the TX54 WebUI as a user with full Admin access rights.
2. On the menu, click System. Under Configuration, click Device Configuration.
The Configuration window is displayed.
3. Click Firewall > Custom rules.
4. Enable the custom rules.
5. (Optional) Enable Override to override all preconfigured firewall behavior and rely solely on
the custom firewall rules.
6. For Rules, type the shell command that will execute the custom firewall rules script.
7. Click Apply to save the configuration and apply the change.
