10. Using IP Alias

• What is IP Alias ?

In a typical environment, a LAN router is required to connect two local networks. The

P-660 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 P-660's single user account. See the figure below.

The P-660 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 P-660 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 P-660 as shown below when the three networks are configured. If the P-660's

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