windows SBS VPN

I have setup a VPN on a SBS2k3 from my home network, I can connect!!! this says a lot! the issue is that the person that actually has to USE the vpn cannot from his home. I use comcast as my ISP he uses wave broadband (if that helps at all) at his home he has an xp pro sp 2 machine, and a vista home premium sp1 both do not work. I have never had it NOT work for some people and work for others...

thoughts?!

issue solved, thanks... I guess

*Slaps Kn1ght*.

People saying "Issue solved" and NOT saying HOW they solved the issue... should be punished :evil:

at the location where they were trying to connect FROM, the router did not allow VPN passthru replaced the router, and we were game.

slap me again and I'll take your cho and shove it up your jin!
