[ale] looking for a very lightweight distro

[jrtroberts at gmail.com (jrtroberts)]

I am looking for a very lightweight distro, something to run on a P2 era 
computer maybe a bit earlier, It only needs to function as a router.  So 
I need to use IP Tables to route between maybe two - five networks, My 
sisters lan/internet connection in her APT and my father's backup 
server(on a separate VLAN) in the house proper.  I am hoping that my 
father has an old box that has room for 2 nic cards.  That seems to be 
the cheapest route at the moment.

Thanks

Joshua
