LAN WAN or DMZ WAN Inbound Rule: Setting Up One-to-One NAT Mapping

In this example, we will configure multi-NAT to support multiple public IP addresses on one WAN
interface. By creating an inbound rule, we will configure the firewall to host an additional public
IP address and associate this address with a Web server on the LAN.
If you arrange with your ISP to have more than one public IP address for your use, you can use the
additional public IP addresses to map to servers on your LAN or DMZ. One of these public IP
addresses will be used as the primary IP address of the router. This address will be used to provide
Internet access to your LAN PCs through NAT. The other addresses are available to map to your
servers.
The following addressing scheme is used to illustrate this procedure:
• NETGEAR FR538G ProSafe Quad WAN Gigabit Firewall
– WAN1 IP address: 10.1.0.118
– LAN IP address subnet: 192.168.1.1; subnet 255.255.255.0
– DMZ IP address subnet: 192.168.10.1; subnet 255.255.255.0
• Web server PC on the firewall's LAN
– LAN IP address: 192.168.1.2
– DMZ IP Address: 192.168.10.2
