	I can't remember the original post, but the idea is that you
route through the debian box (192.168.1.0, I think). If you have another
address in your suse box (you can have as many as you like), you can
then put that address on the same subnet your debian box is, and use
that interface to route the traffice from your Suse subnet to the debian
subnet.

	This could do with a bit of cleaning up, really :)

	No, you can have as many as you like.

	No, not the same address, but an address in the same subnet that
the debian box has. ifconfig is what configures the interface's address,
route is the command that adds routing tables. So you're putting a
gateway in your routing table which is your debian box.

	Check you got all the stuff Chris suggested in the right order.
