Using IP Alias

What is IP Alias ?

In a typical environment, a LAN router is required to connect two local networks. The Prestige 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 Prestige's single user account. See the figure below.

The Prestige 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 Prestige 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 Prestige as shown below when the three networks are configured. If

the Prestige's DHCP is also enabled, the IP pool for the clients can be any of the three networks.
