Client does not connect to server [Wireguard instructions]

[g0djira]

Describe the bug As described in [Wireguard and wstunnel] section I've started

• on server:

  $wstunnel server --restrict-to localhost:51510 wss://[::]:8080
  2024-03-07T15:30:50.003898Z  INFO wstunnel::embedded_certificate: Loading embedded tls certificate
  2024-03-07T15:30:50.004397Z  INFO wstunnel::embedded_certificate: Loading embedded tls private key
  2024-03-07T15:30:50.005180Z  INFO wstunnel: Starting wstunnel server v9.2.2 with config WsServerConfig { socket_so_mark: None, bind: [::]:8080, restrict_to: Some(["localhost:51510"]), restrict_http_upgrade_path_prefix: None, websocket_ping_frequency: None, timeout_connect: 10s, websocket_mask_frame: false, tls: true }
  2024-03-07T15:30:50.005685Z  INFO wstunnel::tunnel::server: Starting wstunnel server listening on [::]:8080

• on client:

  $wstunnel client -L 'udp://51510:localhost:51510?timeout_sec=0' wss://my.server:8080                                                                                   
  2024-03-07T15:31:51.736283Z  INFO wstunnel::udp: Starting UDP server listening cnx on 127.0.0.1:51510 with cnx timeout of 0s   

And that's all, I can't see in logs that client is trying to connect to server and exchange certificates.

To Reproduce

1. Start server with given parameters.
2. Start client with given parameters.

Expected behavior

• server accepting connection;
• server and client doing tls handshake.

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• server: Ubuntu 22.04.4 LTS
• client: Raspbian GNU/Linux 11 (bullseye)
• Version 9.2.3

Additional context wstunnel works as expected in example "Simplest one"

Hello,

Most likely, you misconfigured your WireGuard client configuration. Be sure, the endpoint point to localhost, and to start wireguard after wstunnel is started.

Hello, and thank you for your project!

Isn't Wstunnel supposed to establish connection and handshake even without Wireguard started? Here's my client's wg0.conf:

[Interface]
Address = 172.16.0.2/32
PrivateKey = UM=
DNS = 1.1.1.1

[Peer]
PublicKey = lE=
AllowedIPs = 0.0.0.0/0
Endpoint = localhost:51510
PersistentKeepalive = 20

Fixed by changing localhost to 127.0.0.1 in [Peer] section, client's wg config. O_o

Perfect then, i assume localhost in your /etc/hosts is set properly ? Or resolve to an ip6 address
