9.6 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
) and configure the other subnet in the Network > DMZ > IP Alias
) to use this kind of network setup. You also need to
configure NAT for the private DMZ IP addresses.
