Azure VM Ports Blocked

Question

Dose anyone know if port 7300 is being blocked by the Azure Platform like port 25? I have allowed this port though to the VM however i cannot access it at all.

Many Thanks

There shouldn't be any restriction on port 7300. To test this, I created a Linux VM and enabled SSH connectivity on port TCP 7300. I was able to connect and remain connected without issue.

To diagnose the issue with port 7300, you can follow the steps mentioned here. This will allow you to troubleshoot and see if there are any NSG rules which might be unexpectedly blocking that port. For comprehensive network troubleshooting you can use the Network Watcher to run testing and diagnostics.

If you are still facing issues let me know what service you are running and what response you are getting when testing with telnet or netcat.

Hope this helps! Let me know if you have any more questions or need further assistance.
