Cannot establish network connection from WSL to Windows host (could be blocked by firewall)

Every time I restart my laptop and intellij idea IDE, I get following error:
This happen when idea trying to index.

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

As a workaround I did the step as per the instruction in https://jb.gg/wsl-firewall and It works. Bur I have to do it each and every time I restart the machine. I need to know, can we disable firewall rules for intellij idea IDE and WSL processes permanently?
