Minecraft VPN server problem

I can make my own server and connect to it with ease, and my friend can do so likewise. However, I would like to join my friends server, but I cannot connect to his server but he can.

If I have my server up and running while I try to connect to his, then I will be joining my own multiserver instead. But if he has his server running and joins mine, then there is no problem. And when I use the direct connect with his VPN IP it just ends up in a connection timed out.

It seems like I can only recognize and join my own server no matter what I do. But my friend has none of these problems. Anyone got some tips?

If I understood corectily, you are putting the ip of his VPN into the direct connect box of minecraft multyplayer. you must connect to the vpn then put the ip of the server from your friends network into direct connect.

I would recommend using Tunngle over Hamachi. It was designed specifically for tunneling video games, and from personal experience, does a much better job at it than Hamachi.

However, to actually answer your question: it is likely a firewall or adapter-priority issue. Have him turn his Windows firewall off, and make sure Hamachi is set as the highest-priority adapter in Windows.

Alternatively, just host the game outside of Hamachi, and have him forward the correct port on the router.
