8.6 DMZ Private and Public IP Address Example

The following figure shows a network setup with both private and public IP addresses on the DMZ. 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 server F use private IP addresses that are in one subnet. The private IP addresses of the LAN and DMZ are on separate subnets. The DMZ port and connected servers (D and E) use public IP addresses that are in one subnet. The public IP addresses of the DMZ and WAN are on separate subnets.

Configure both DMZ and DMZ IP alias to use this kind of network setup. You also need to configure NAT for the private DMZ IP addresses.
