I have 2 networks each with a linux box as the gateway to the internet.
At the moment they are VPN'd together, but are close enough to get a
cable run and I'd like to connct them like this to make it quicker
so each linux box will have 3 nics in it.
My question is possibly a dumb one! But what should the IP for the 3rd
nic in each box be?
The networks are:
network - linux box internal address
Box 1) 10.0.12.x/24 - 10.0.12.1
Box 2) 192.168.12.x/24 - 192.168.12.1
Should the 3rd NIC in the box 1 be on the 192.168.12.x range, and vice
versa but wouldn't that confuse the other network as it would think that
it is a local IP when it wouldn't be.
Should they both be on a different range althogether? And then set the
routing up on each.
ie 3 NICS in each
If it was 2 networks with one linux box it would be easy, just not sure
how you'd connect the two boxes together....
Any advice appreciated!
