Note:
In Non-NAT mode, all the NAT forwarding rules will be disabled.
Classic Mode
It's the combined mode of NAT mode and Non-NAT mode. In Classic mode, the router will first
transport the packets which are compliant with NAT forwarding rules and then match the other packets
to the static routing rules. The matched packets will be transmitted based on the static routing rules
and the unmatched ones will be dropped. In this way, the router can implement NAT for the packets
without blocking the packets in the different subnet of the ports.

Tips:
It’s allowed to set the IP addresses of both the WAN ports within the same subnet. However, to
guarantee a normal communication, make sure that the WAN ports can access the same network,
such as Internet or a local area network.
