Greetings!

I have recently been trying to set up a VPN connection with someone other the internet using the built in VPN wizard in XP but i cant seem to connect to this person. we have both set up our wizards for him to have incoming connections enabled and me outgoing, and vice versa but absolutely no luck, i can ping his public IP however. is there any other steps i need to take to be able to connect? or is this VPN thing not used for what im trying to do.. would appreciate the help :) thanks
