Hello my guru fellows...here I am...yet another time, to ask for your help regarding this nice OS also known as Linux

Ooooooook: here's the question...
I have a linux box which acts as a router with Slackware 10.2 on it.
iptables is configured so I can share my connection with another machine on which I use that shiny-looking-sexy-game-console-soft XP.
Now I wanted to try the ipv6 protocol and I found some tutorials on how to do that but if I configure ipv6 on the router, will it be possible to share my connection with win-lost?
I hope I was clear enough

Thanks to anyone...any help appreciated
