12.6 Enabling Firewall
The ordering of your rules is very important as rules are applied in turn.
The default rules allow LAN-to-WAN traffic and deny traffic initiated from WAN-to-LAN. You may block
traffic initiated from the LAN by configuring blocked services in the Services screen. You may allow traffic
initiated from the WAN by configuring port-forwarding rules, one-to-one/many one-to-one mapping rules
and/or allow remote management.
