Using IP Alias
 What is IP Alias?
In a typical environment, a LAN router is required to connect two local networks. The ZyXEL Device can
connect three local networks to the ISP or a remote node, we call this function as 'IP Alias'. In this case, an
internal router is not required. For example, the network manager can divide the local network into three
networks and connect them to the Internet using ZyXEL Device's single user account. See the figure below.
The ZyXEL Device supports three virtual LAN interfaces via its single physical Ethernet interface. The first
network can be configured in menu 3.2 as usual. The second and third networks that we call 'IP Alias 1' and 'IP
Alias 2' can be configured in menu 3.2.1-IP Alias Setup.
There are three internal virtual LAN interfaces for the ZyXEL Device to route the packets from/to the three
networks correctly. They are enif0 for the major network, enif0:0 for the IP alias 1 and enif0:1 for the IP alias 2.
Therefore, three routes are created in the ZyXEL Device as shown below when the three networks are
