Use two USB ethernet ports. They're cheap, most of them work quite
well with Linux, they're handy for other uses, and easily configured
for little private, non-routable VLAN. Since most modern such ports
are GigE compatible, the connections are hermaphroditic, and you won't
even need a crossover cable. And the USB ethernet ports are invaluable
when confronted with broken wireless environments. I always keep one
in my "emergency computer widgets" bin.
