source IP address can be transported by NAT, whereas the packet with 20.31.76.80 as its source IP address will be dropped.

zNon-NAT Mode

In this mode, the Router functions as the traditional Gateway and forwards the packets via routing protocol. The Hosts in different subnets can communicate with one another via the routing rules whereas no NAT is employed. For example: If the DMZ port of the Router is in WAN mode, the Hosts in the subnet of DMZ port can access the servers in Internet only when the Static Router rules permit.

Note:

In Non-NAT mode, all the NAT forwarding rules will be disabled.

zClassic 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.
