[wplug] one armed router

[Keith Wolters]

Can anyone tell me if Linux can be used as a one armed
router?  By that I mean that a Linux box would have
one thernet card with two (or more) IP addresses
associated with the card and when it received a packet
for a different network from one one it was sent from
it would rewrite it and send it out on the same card
it was received on.

I'm looking to do this because where I work we use
192.168.0 as our network and I'd like to migrate
either to multiple class C networks or to a subnetted
class B network but to ease the transition I thought
that if we could run two networks over the same wires
for some time we could seperate the renumbering task
from the rewiring task.
