Router firewall
The Router firewall page is used to enable or disable the in-built firewall on the router. When enabled, the firewall performs stateful
packet inspection on inbound traffic from the wireless WAN and blocks all unknown services, that is, all services not listed on the
Services configuration page of the router.
With respect to the other Routing options on the Networking page, the firewall takes a low priority. The priority of the firewall can be
described as:
DMZ > MAC/IP/Port filtering rules > MAC/IP/Port filtering default rule > Router firewall rules
In other words, the firewall is of the lowest priority when compared to other manual routing configurations. Therefore, a MAC/IP/Port
filtering rule takes priority in the event that there is a conflict of rules. When DMZ is enabled, MAC/IP/Port filtering rules and the
router firewall are ignored but the router will still honour the configuration of the Remote router access control settings listed under
Administration Settings.
