This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
Right now Signal Service runs the Let'sEncrypt manager on port 80
and a gRPC server on port 10000. There are two separate listeners.
This PR combines these listeners into one with a cmux lib.
The gRPC server runs on either 443 with TLS or 80 without TLS.
Let's Encrypt manager always runs on port 80.
