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.
