my friend and i are trying to connect our computers together using a VPN but when ever he tries to log into my computer, the connection times out. i have DHCP enabeled on ym network, but my computer has its own IP and i have DMZ enabeled forwarding everything to my IP. are there some ports i need to forward in my router to make this work?

If you have setup your computer as a dmz then you have all ports redirected to you computer. What version of windows are you running and what are you using to terminate the vpn connection? Also the ports you need to forward are different for each type of vpn.

Also make sure that you are both using different ranges of IP address's eg 192.168.0.x for you and 192.168.1.x for your friends network.

i know that dmz is suppose to forward everything to me, but i still have to forward ports for things like bit torrent and emuel to get thoes to work.

im using windows xp pro, and im trying to use the vpn client built into windows. my IP is 192.168.1.15, and his is something else.

Windows VPN client, as in client not server. What are you using to setup the vpn? eg router with VPN server (not passthrough), windows 2000 server, smoothwall etc etc

Also setting up a box in a dmz is risky business for a home user. Its a much safer practise to simply forward all ports that you need brought to that computer from the internet. The ports you need redirected depend on which type of vpn you want to setup, PPTP - TCP 1723, L2TP UDP 1701 & IPSEC - UDP 500. So for L2TP over IPSEC you would have to forward UDP ports 1701 and 500.

to setup the VPN im using windows xp plus my linksys router. i have VPN passthrough enabled, and im forwarding port 1723 TCP. we got the VPN kinda working now. my friend can connect, but then imediatly gets booted fomr the internet and the VPN.
