GameLinkSafeCLI is an Open Source project that aims to connect 2 machines through WebRTC and share ports. It is an alternative to ngrok/hamachi with TCP/UDP support. No account required.
This programm is a CLI, may not be easy for all users. There isn't a GUI implementation at the moment.
You can use the software as it comes but if you are behind a strong firewall, a strict NAT or searching for more security you may want to have your own TURN server. If this is the case you can rent a TURN server or self-host it using coturn
- TCP/UDP support
- No accounts
- Plug & play config
- Windows/Linux/MacOS support

Shows all commands with examples
./gamelinksafecli --help
Host shares tcp 8000 port
./gamelinksafecli --role host --protocol tcp --port 8000
Client setup tcp tunnel on port 5000
./gamelinksafecli --role client --protocol tcp --port 5000
Now it should appear some messages with instructions and connection codes. Finally copy and paste the generated codes between peers.
The resulting connection will work like this:
Host (TCP 127.0.0.1:8000) <-> Client(TCP 127.0.0.1:5000)
By default GameLinkSafe uses a dynamic public STUN server list but you can specify STUN / TURN servers using a servers.yml file in the same directory as the executable.
This is an example of use:
# file: servers.yml
iceServers:
# Public STUN servers
- urls:
- stun:stun.l.google.com:19305
- stun:stun.l.google.com:19302
- stun:stun.ipfire.org:3478
# TURN server with UDP transport
# - urls:
# - turn:turn.example.com:3478
# username: user1
# credential: pass1
# # TURN server with TCP transport
# - urls:
# - turn:turn.example.com:3478?transport=tcp
# username: user2
# credential: pass2
