I wasn't very clear in my last post. You'll need to separate out that
small block into different subnets, as they're on different interfaces.

Actually, it's probably as easy to do this. Set the 192.168.1.x IP
address on the test machine, then try pinging eth3's IP address from the
test machine. That should work. Then try the gateway on the same subnet.
That should also work.

Once that's working, then you should be able to do a DNAT on the
firewall to send packets coming in on eth3 to the test machine
(192.168.1.x).
