Incoming traffic is translated back for delivery within the internal network However the router will drop all the packets whose source IP addresses are in different subnet of LAN port For example If the LAN port of the router is set to 192 168 0 1 for IP address and 255 255 255 0 for the Subnet Mask then the subnet of LAN port is 192 168 0 0 24 The packet with 192 168 0 123 as its source IP address can be transported by NAT whereas the packet with 20 31 76 80 as its source IP address will be dropped e Non 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 11 Note In Non NAT mode all the NAT forwarding rules will be disabled e 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 o
