2.2.4 Firewall Settings

The system IP firewall has a default "allow all" policy. To enable the firewall, the
customer needs to create a firewall rules file on the product file system named
/mod/tsc/firewall.rules. There are example firewall rules files on the product in the
directory /usr/tsc/site/firewall. Example rules files may be copied to the correct location
and edited on the product using 'vi'. Once the rules file is setup, reboot the product.
Note that miss-configuration of the firewall can lock out network access to the product.
If that occurs, the firewall may be disabled by using a USB command port adapter, and
executing the command firewall --disable. This removes the current firewall rules and
resets it to immediately allow all traffic exposing the device.
The firewall is the standard FreeBSD IPFW.
