8.3 DMZ Public IP Address Example
The following figure shows a simple network setup with public IP addresses on the WAN and
DMZ and private IP addresses on the LAN. Lower case letters represent public IP addresses
(like a.b.c.d for example). The LAN port and connected computers (A through C) use private
IP addresses that are in one subnet. The DMZ port and connected servers (D through F) use
public IP addresses that are in another subnet. The public IP addresses of the DMZ and WAN
ports are in separate subnets.
