I did the software modification proposed on www.xbox-linux.com to get a version of Debian called Xebian running on my Xbox. My laptop is running Redhat 9 and is connected to the LAN here at my school through it's internal network card. However, I have an external usb-ethernet card and a crossover cable and I want to get the xbox online through my computer (there isn't an extra ethernet jack).

The xbox is configured with ip 192.168.0.5, subnet mask 255.255.255.0, and gateway 192.168.0.4, my laptop-to-xbox connection (eth1) is configured 192.168.0.4, subnet mask 255.255.255.0, and no gateway. The lan connection (eth0), gets its information through dhcp, but i seem to have a stable ip of 147.253.107.95

i tried running a firewall setup script that said it would enable the routing, but i can't ssh out of the xbox even using hostnames or ip addresses. i can, however, ssh into the xbox through eth1, and ssh back into my machine from there.

any ideas on how to get my laptop to pipe eth1 through eth0 would be greatly appreciated.

Try the following... (if you're interested, ask me for documentation links or look yourself on www.tldp.org ... )

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 147.253.107.95

Note that if it subsequently turns out your external IP isn't always this, you will have to change the command.. there is a form that can deal with dhcp assigned addresses, but there's no need to confuse you with it atm

(edit: oh, these commands should be run on your externally connected machine... as long as your xbox has that as a router, it should work fine )

that did it. thanks a lot.
