you´re right, that´s exactly the thing I´m trying to set up here. And if it works, I can finally do a full NAT-routing to my Dreamcasts MODEM (I´m a poor 33.6K euro-user), since I can just hook up a modem to my pc and connect it to the DC, it will give me Internet access without any problems if configured correctly. Sadly, my last NAT software made my system crash, PSO-sessions are slightly frustrating if you lose your character every 5 minutes.
