OK, I will change this.

Change my FreeBSD box's IP address to 192.168.1.2? Can you explain the
logic behind this? I thought I would need to keep it on the same subnet
as the rest of the LAN, otherwise how will it communicate.

Yes, I think that depicts it. The FreeBSD box has the router connected
to it. The FreeBSD box has another NIC which connects to a hub. All the
Windows boxes are connected to the hub.

OK.

They all have a default gateway of 192.168.0.5, but won't this be wrong
if I change the IP address of the FreeBSD box to 192.168.1.2?

All the Windows boxes have an IP address like 192.168.0.x

Well I'm about to leave for work, but hope to have another fiddle when I
get back. Thanks for the help!
