7.5 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.

7.6 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 one subnet (either the public or the private) in the Network > DMZ screen (see
