 That'll do nicely, Richard, I'm going to be using OpenBSD on one or two
of the new (5 year old :-) machines I'm getting.

The reason for this question is that I'm cheap, and don't want to buy
another hub, when I can get cheap NICs, and have Linux or OpenBSD lying
around looking useful.

 I want the two machines i.e. [(eth0)192.168.0.5+(eth1)192.168.0.6] and
[192.168.0.7] to be accessable with modifying the rest of my already
established 192.168.0.0 network.

 Going on what is being said here regarding just adding a gateway to the
routing tables on 192.168.0.7, 192.168.0.7 will be able to communicate
with the rest of the network through the machine on 192.168.0-.5/.6.
 Problem is getting all the other machines know that 192.168.0.7 is the
other side of another machine...

 ...This isn't making much sense.

 Basically the question is: If I already have a default route set on all
machines (to firewall/NAT box), can I add a second gateway and expect
the existing machines to search through gateway 1 and/or gateway 2 to
find a machine that isn't on the hub?

 *Scratches head*

 If this is too much of a problem, I can live with having the network
setup so that access to machine #6 is through #5 explictly, rather than
transparently.

Baz.
