You can use netplay with the following methods:

Port Forwarding

1. Download rmg-netplay-server
2. Port forward the ports stated in the rmg-netplay-server README
3. Create a JSON file with something similar to the following contents, but using your public IP instead of a local one:

{
  "some-server-name": "127.0.0.1"
}

If you want to add multiple servers instead:

{
  "some-server-name": "127.0.0.1",
  "some-server-name-2": "127.0.0.1"
}

4. Store the JSON file or upload it somewhere
5. Enter the JSON file path or URL in the "Server list URL" text box in the RMG settings dialog
6. The specified servers in the JSON file should appear in the RMG GUI

Tunneling Software

1. Download rmg-netplay-server
2. Download Radmin VPN
3. Run and create or join a network in Radmin VPN
4. The host should run rmg-netplay-server
5. The server should show up as local-server within the RMG GUI
