Windows firewall blocking port for WSL2 development

Trying to setup a Java SDK running in WSL2. I can successfully do a mvn install and compile but
when trying to run the application I get this error:

Cannot establish network connection from WSL to Windows host (could be blocked by firewall). More details: https://jb.gg/wsl-firewall

The selected port is blocked by windows firewall and my PC is under company system administration (sad, I know) so I cannot make any firewall changes.

This port is also selected at random it seems, so I cannot create a firewall rule based on ports only. 

Is there a way to tell IntelliJ what port to use instead of selecting a random port? We have a few unblocked ports for development.
