So, I could be able to open a server like the NetworkManager HUD open with matchmaker. I'm able to open the server(receive income connections), but was not able to create the host part, where the server can play and the client too.

Already saw the network projects, but couldn't find anything useful.

I would like to know how I could do it with a custom GUI, and if is there a way do lower the ping, because I live on Brazil, and the ping with the matchmaker is very high
