Gears LAN Party... NEEP HELP!!!

I'm attending a Gears of War Lan Party today nad need help. I own 2 360's, 2 ethernet cables, and 2 copies of Gears.

I know that 4 360's are needed to do a LAN match for 8 players, but there's one thing I'm not sure of. How do we get the 360's linked together? Thanks in advance.

you just need to plug a cable from each 360 into a hub/router

*note: they all must have the latest update
