When proxying traffic through a CF’s A record, what ports should I choose as incoming in order for my port-forwarding rules to work? I know Cloudflare has a limited port number it can proxy, but I need to know where is Cloudflare trying to hit my origin IP, by port? The connection client-Cloudflare succeeds, but I don’t know what port should I keep open in order for Cloudflare to hit my Origin IP successfully
I’m trying to receive TCP connections (Non-http) to a port of my choosing, at my origin.
Hi, thank you. I know what ports Cloudflare uses, but I’d like to know what port is Cloudflare trying to reach at the Origin IP. I’m not using any proxy, just port forwarding rules accepting incoming connections (That’s where I need to specify an open port in order to let Cloudflare successfully hit the internal IP). I hope this makes sense
For no special reason, I just tried to accept incoming connections for example, to the router’s 2052 port, and at the client-side, also trying to connect to Cloudflare’s 2052 port, but I’m not reaching anything yet
I’ll need to read the docs again thoroughly, because I’m not even sure what that means. I am succesfully sending TCP through Cloudflare. I never achieved this with Cloudflared, but with the normal proxy I’m okay now. By the way, my A record had an underscore in the name, and that’s why it didn’t work
