Online problem ping

[hassaan_noob]

I have mugen game. It works with tunngle and hamachi (which i have tried with Mugen and Tekken 6 PPSSPP emu) . But my friend who plays with me has 500 ping. Lags very much.
But kawaks(neogeo emu) works good with Kaillera.

I have tried 2 ways.
1: Kaillera.
2: Tunngle/hamachi.
Kaillera is a way to play on a server. Masterserverlist. Join any server. You rfriend connects on that server. You host game, and he jons you. Play. We both connect to 1 server(ping mine:200, his ping:250) . Works great.
Tunngle/hamachi do not connect to a server. It is peer-to-peer way of online. My destination is far away from my friend so he gets 500 ping. Mine = 5 ping. Very laggy.
