I am confused by the Firewall function of my CGN3 router.
Look at the screen shot:
I thought the Firewall functionality is about restricting LAN-to-WAN traffic since the router in "GATEWAY" mode automatically does not allow any traffic coming from WAN-to-LAN (because the computers on LAN are using private IP addresses).
SO if this is the case, why enabling minimum (or typical) security in the Firewall page sets WAN-to-LAN traffic to allow All? How is this even possible since you need a specific port forwarding rule to make WAN-to-LAN possible?
Am I missing something here?
The firewall settings are inbound. The publlic to private IP Address conversion is a NAT function. Service filtering allows you to set up rules for LAN-to-WAN traffic.
