Detailed description

In short:

1. You run a special program called "Communicator" on a remote host

2. You create a game server implementing the base game logic and run it on the same remote host along with the Communicator

3. You create a client Unity based application to be running on players host. This Front End connects to the game server via the Communicator

The package contains a C# based wrapper DLL (assemply) to write client-server applications connected via communicator.

Test programs and the Communicator itself are available to download for free here. You can get them and run locally or run the Communicator on remote address, test connections etc... (see the description for details).
