Since I got DSL, via an Ethernet modem, I can't host JJ2 servers anymore (they are pinging) and I automatically time-out after a minute or so when joining one. Since I never had this problem until I got DSL, I think it's coused by the modem. I tried to find some place where I could set port-forwarding, but it isn't there.

I have an Alcatel Speedtouch ADSL 500 series modem, connected to a Sitecom network card. I'm using Windows XP home edition. In the modem setup, there's no place I can set port forwarding. Anyone know the solution?
