Chapter 9 Network Address Translation (NAT)
IAD User’s Guide
116
The following example has two web servers on a LAN. Server A uses IP address
192.168.1.33 and server B uses 192.168.1.34. Both servers use port 80. The
letters a.b.c.d represent the WAN port’s IP address. The IAD translates port 8080
of traffic received on the WAN port (IP address a.b.c.d) to port 80 and sends it to
server A (IP address 192.168.1.33). The IAD also translates port 8100 of traffic
received on the WAN port (also IP address a.b.c.d) to port 80, but sends it to
server B (IP address 192.168.1.34).
Note: In this example, anyone wanting to access server A from the Internet must use
port 8080. Anyone wanting to access server B from the Internet must use port
8100.
