What does a person need to setup a VPN? Need a VPN server?, Need a Router?, If I wanted to setup one up, what do I need to do it? I want to setup one so I can access a friends (vice versa) computer and I need to know what I need in order to do this. Or if I want to access my computer from anywhere else, can I do this?
Many home routers now feature VPN capabilities. Windows server editions have VPN capabilites as does most *nixes. You can also use VNC although it's a little slow, and tightVNC is IIRC free for windows. I also think that you can use an XP feature (remote assistance, I think it's called), but I don't have XP and have never tried it.
