VPN Issues!

[m3gau]

Hey Guys.
I've just come to Uni and am trying to set up VPN with my dad at home. He's running it off of a windows machine on a Draytek Vigor 2800 router. He can access it from his windows machine at work absolutely fine but from my Mac here at Uni i can't. I use the Internet Connect Program and put in all the settings my dad uses and it comes up saying negotiating then comes up with an error message saying it could not negotiate a connection with the remote PPP server.
Is there something on the Mac I haven't set up or does anyone have any ideas on how to make this work!

Thanks

I presume you've typed in the server address, be it a fixed IP Address or DynDNS name properly.

Not really that much to set apart from that. Try playing with the encryption settings.
