Give internet to another computer via LAN

[Dbugger]

Hello guys,

I am using a USB DSL modem to get internet in my ubuntu directly, and Im in a wired LAN with my brother's computer (which runs windows, but I dont think this matters)

Is there anyway I can give him internet access?

Thanks!

this guide is good for standar situation but It gets kinda confusing in my case
when I make a "ifconfig" i get all this interfaces:

wifi0, ppp0, nas0, lo, eth0, ath0

which should I use for each thing??

Edit:

Just guessing at this point:
eth0 = wired connection
ath0 = ???
ppp0 = DSL device?
lo = loopback device
wifi0 = wireless (tough to guess )
nas0 = ??? NAS storage device?

Interesting to note - besides standard lo, only nas0 and ppp0 have IP addresses.
