As part of implementing #1600

We probably need more ports open and we should document which ports are required for each scenarios:

With embedded DERP:

  • 80 -> for generate204
  • 3478 -> STUN
  • 443 -> Headscale + DERP

With Letsencrypt:

  • 80 -> ownership check

Standard:

  • 50443 -> gRPC
  • 9090 -> /metrics

Is it possible to change the usage of port 80. I have headscale listening on below

server_url: https://hs.mydomain.com:8443

and caddy web server on port 80 and 443. The clients seem to send the below request to port 80 which gets logged in caddy as errors instead of reaching headscale. Is the below request only used with embedded derp?

@balki commented on GitHub (Apr 8, 2024): Is it possible to change the usage of port 80. I have headscale listening on below ```yaml server_url: https://hs.mydomain.com:8443 ``` and caddy web server on port 80 and 443. The clients seem to send the below request to port 80 which gets logged in caddy as errors instead of reaching headscale. Is the below request only used with embedded derp? ```json { "level": "info", "ts": "<timestamp>", "logger": "http.log.access.log0", "msg": "handled request", "request": { "remote_ip": "XX.XX.XX.XX", "remote_port": "40362", "client_ip": "XX.XX.XX.XX", "proto": "HTTP/1.1", "method": "POST", "host": "hs.mydomain.com:80", "uri": "/ts2021", "headers": { "User-Agent": [ "Go-http-client/1.1" ], "Content-Length": [ "0" ], "Connection": [ "upgrade" ], "Upgrade": [ "tailscale-control-protocol" ], "X-Tailscale-Handshake": [ "<base64 encoded binary data>ggwE=" ] } }, "bytes_read": 0, "user_id": "", "duration": 0, "size": 0, "status": 0, "resp_headers": { "Server": [ "Caddy" ] } } ```
