11 months agoCF tunnels are layer 3, not 7 and they have support for web sockets. It’s basically wireguard VPN with a few extras built on top.

No, but I thought I clarified that when I said it’s basically wireguard VPN which operates using tcp/udp (layer 3.) layer 7 is stuff like https. CF tunnels are lower level.
Page you linked is missing the layer between CF and source server so it doesn’t indicate layer. You can lookup wireguard protocol if you want more details.
