GOSTC NAT traversal

The GOSTC extension connects the GOSTC client to its service and provides NAT traversal. Install gostc and obtain a client key from the service website.

Service websites

• One-KVM service: https://gostc.mofeng.run
• Official GOSTC service: https://gost.sian.one/

Steps

1. Register and sign in to the service, completing email verification if required.

3. Open Settings -> Extensions -> Remote access -> GOSTC, enter the server and key.
4. Confirm TLS, click Save, then Start. Use View log to confirm the connection.

Add port forwarding on the service

1. Open tunnel management or port forwarding and create a forwarding tunnel.
2. Select a node, plan, and the client you created.
3. Set the local address to 127.0.0.1 and the port to the One-KVM web port (usually 8080).
4. Save and use the remote address shown by the service.
