isn't that true with WireGuard/Tailscale too?
- xena 4y agoTailscale employee here. Tailscale has a fallback that does connections to a relay server called DERP. DERP works over HTTPS, so if you can't access the outside world via HTTPS then you have much bigger problems than Tailscale not working.
- anderspitman 4y agoIs DERP raw HTTP or based on WebSockets?
- ignoramous 4y agoderp seems to be its own protocol. tailscale seems to prefer websocket transport for derp frames: https://github.com/tailscale/tailscale/blob/505f844/derp/derphttp/derphttp_client.go#L5 https://github.com/tailscale/tailscale/blob/505f844/derp/der...
