Setting up hamachi for OrbitLegacy

I have orbitlegacy by madboy source code. But i don't know how to set up hamachi and the sources. I opened hamachi and made it on. Then copy ipv4 and paste it on the sources. But when i try to execute the server all it's ok, if i try to execute the cliet it tell me "Can't call the server". Why this? Who can help me?
