7.4 DMZ IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface.
The ZyXEL Device has a single DMZ interface. Even though more than one of ports 1~4 may
be in the DMZ port role, they are all still part of a single physical Ethernet interface and all use
the same IP address.
The ZyXEL Device supports three logical DMZ interfaces via its single physical DMZ
Ethernet interface. The ZyXEL Device itself is the gateway for each of the logical DMZ
networks.
The IP alias IP addresses can be either private or public regardless of whether the physical
DMZ interface is set to use a private or public IP address. Use NAT if you want to make DMZ
computers with private IP addresses publicly accessible (see
information). When you use IP alias, you can have the DMZ use both public and private IP
addresses at the same time.
"
Make sure that the subnets of the logical networks do not overlap.
