Vitural Network Interfaces

Vitural Network Interfaces

[David Jackson]

A common reframe on http://linuxquestons.org is:

4 boxes each with one(1) nic card and each having a seperate connection through a router to the internet (CABLE/DSL).

IN THEORY could you set up LAN using a virtual network interface on that
one nic card i.e.

eth0 ----->router ---->internet
eth0:1 --->LAN


Calk this one up to lack of sleep :)

Yeap, we utalize this for talking to power control devices and the like.

Nathan --
As far is the cable internet and router is concerned
Box A =  eth0 --192.168.0.1 -->|router (port 1)| -->206.196.128.1:1 ->internet
Box B =  eth0 --192.168.0.2 -->|router (port 2)| -->206.196.128.1:2 ->internet

and the LAN would still be 192.168.0.x?
Would you need to add a hub between router and the boxes?

TIA,
David

It depends on the config of the router. Since most of us don't have
control over our upstream routers the most reliable config would be to use
a hub/switch between you and the router.
