Quick VPN Question

Evening, guys.

I've got a quick question regarding setting up a VPN on a TP-Link TL-ER604W. Long story short, I'm currently at a university whose network prevents any form of port forwarding to the spare system have in my room. A few of my friends from home (who are now across the country) want to do some things that I'm trying to set up a server for; they originally wanted to use Hamachi, but I've got a TP-Link VPN router here which seems to be capable of forming a VPN with the native client built into Windows. I can't for the life of me get anything to connect. Bear with me here - I'm trying my best to understand network topology a bit better, but it's tough for someone with nothing but Google and a overly assumptuous manual to work with.

I'm trying to set up a PPTP server as a client-to-LAN tunnel with 10 max connections, and no encryption, with an IP address pool of 10.1.0.0 to 10.1.0.9. Along with the account name and password, these are the only meaningful values I have to work with on the router itself unless I want to go to L2TP or IPsec. I've made a new VPN connection in Windows (connected to the university wireless, not on the same subnet as the router itself) using Point-to-point tunneling, and accepting basically any form of encryption. I can only assume the "Internet Address" the setup is asking for is the WAN Gateway listed by the router itself (on the Network > Status page).

What am I missing here? The connection times out before throwing an "Error 807: The network connection between your computer and the VPN was interrupted."

Any thoughts? I'll be glad to list any more information needed if you let me know.

Much appreciated!

If you want to make "server", you need a way for "clients" to reach your server. Without any intermediate, your friends have no way to reach your sever (since they can only reach your uni' external IP address, and there is no path toward your "server").

You might be able to achieve something with an intermediate - that is, a "VPN connector" outside your uni, but under your control. Both your server and your friends "dial into" that VPN server, thus forming a private network.
