Example 3: Multi-NAT configuration
Situation: You want to configure multi-NAT to support multiple public IP addresses
on one Option port interface.
Solution: Create an inbound rule that configures the firewall to host an additional
public IP address. Associate this address with a web server on the DMZ. 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. One of these public IP
addresses is used as the primary IP address of the controller. This address is used to
provide Internet access to your LAN PCs through NAT. The other addresses are
available to map to your DMZ servers.
The following addressing scheme is used to illustrate this procedure:
