I have created a Windows Firewall exemption via an Inbound Rule allowing UDP traffic through local port 51820 from any remote port.

I have validated via the Windows Event Viewer that my simple PING test is being dropped and I corresponded the filter-run-time-id to the Windows Firewall rule, Query User.

I read that other people fixed the issue by modifying Group Policy to apply local firewall rules. In my case, this value is already set to Yes for Public Networks (the type of network my PC is connected to.)

What else can I investigate? Thanks

running a PING will not guarantee the check if the port is open, PING will use icmp protocol, not UDP.

One way you can check is using nmap from a linux computer or just try with one of the online tools like this one to see if your port is actually open.

for what I remember what you did should be enough, enabling the inbound rule and applying the local policy to public networks, but in case we are missing something

Also as a test you can try disabling you windows firewall temporarily to see if your service is responding correctly over that port.
