When setup with tunnels, cloudflare doesn’t see any media traffic. Cloudflare only needs to serve the auth and handshakes. The actual traffic is IP to IP, TLS encrypted if you setup a domain correctly. Or just use something like tailscale that sets up the certificates and domains for you.
Cloudflare doesn’t allow streaming large quantities of data through their tunnels. At least it’s against their ToS.
