Firewall Protection and Content Filtering 4-15

v1.0, March 2008

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.

To configure the FVS338 for additional IP addresses:

1. Select Security from the main menu and Fir e wall Rules from the submenu.

2. Click Add under the Inbound Services table. The Ad d LAN WAN In boun d Service screen

will display.

3. From the service pull-down menu, select the HTTP se rvice for a Web server.

4. From the Action pull-down menu, select Allow Always.

5. In the Send to LAN Server field, enter the local IP address of your Web server PC.

Figure 4-8

Tip: If your ISP allows you 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. One of

these public IP addresses will be used a s 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.
