For this example, an internal web server uses a dns record pointing to the server’s external public internet address.
External users resolve the address, connect to the external interface of the firewall and. To enable clients on the internal network to access the public web server in the dmz zone, we must configure a nat rule that redirects the packet from the external network, where the original routing table lookup will determine it should go based on the destination address of 203. 0. 113. 11 within the packet, to the actual address of the web server on the dmz network of 10. 1. 1. 11.
