This describes how to configure multi-NAT to support multiple public IP addresses on one WAN interface of a NETGEAR FVX538 or FVS338 ProSafe VPN Firewall.
By creating an inbound rule, the firewall is configured to host an additional public IP address, and associate that address with a Web server on the LAN. This can be done for many additional addresses by creating an individual rule for each.
This procedure was developed and tested using:
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 is used as the primary IP address of the router. This address is used to provide Internet access to your LAN PCs through NAT. The other addresses are available to map to your servers. The other addresses do not have to be contiguous, or on the same subnet, but your ISP must provide a routing path to them.
Your rule now appears in the Inbound Services table of the Rules menu (shown below). This rule is different from a normal inbound port forwarding rule, in that the Destination box contains an IP Address other than your normal WAN IP Address.
From a PC on the Internet, type http://<IP_address>, where <IP_address> is the public IP address you have mapped to your Web server. Your Web server’s home page appears.
