For the school project, I need to have a publicly accessible small TFTP server. I have created a new instance on Azure with Ubuntu 20.04 and installed a TFTP server on it. For now, I have set any traffic on port 69 (in/out) for the TFTP server and allowed any traffic on ports 1024-65535 (in/out). I can connect to it with tftp <ip>. Running tftp> status shows that I’m connected. But when I try to download the request gets timed out.
