I’ve been reading about the Telnet topic on the forum, but I can’t find the solution.
I have a server which is linked to the tunnel. I can access the server’s web platform via HTTPS, but I need connectivity to a port (51212) via Telnet.
I tested by opening the port on the router and accessing through the public IP, and this solution works, but I want to use it via a Zero Trust tunnel.
From what I’ve read, cloudflared blocks Telnet communications among others, and I don’t know how to allow these communications if that’s the case.
I am managing communications directly from the Zero Trust platform. I haven’t touched anything on the local application.

To enable connectivity to a specific port via Telnet through a Zero Trust tunnel, you require cloudflared on the client side as well. Follow these general steps:
Download and set up cloudflared on your client device.
Connect to your server through a Tunnel using the cloudflared access tcp --hostname yourHostName --url tcp://localhost:51212 command in your local terminal.
Please note that Telnet is not secure and it’s generally recommended to use more secure protocols like SSH.
Hello you can do this via this article. Arbitrary TCP · Cloudflare Zero Trust docs It will require that the devices connecting have cloudflareD installed.
Hello! Thank you for the help.
The terminals send information through port 51212 and receive information through port 51211.
