Unity Editor has not permission on UDP port

Question

Hello.

I have the next problem.

I'm developing a small game that use UDP server for multiplayer.

When I run the game inside Unity Editor is not working.

After many resurches I found that the UPD socket that create the client (the game) has not permision on the firewall.

When I build the game and run it at the same PC works fine and the UPD socket has permision.

Some extra data:

I use Windows 10.

I run Unity as adminstrator.

I have open/pemited the ports (input and output) in the firewall configuration needed for my game.

I have open/permited the conections of Unity.exe in the firewall.

What @aress mean with his solution is:

Go to firewall settings -> Advanced settings -> Invound Rules -> Your Unity version -> Allow

Windows fireqall

In my case, the rule was set to public, so I had to also modify it in "advanced" to allow private connections
