@echo off
REM DOCKER / WSL2 / HYPER-V Systems with sometimes blocked ports you don't understand why are blocked.
REM TL;DR It's WinNAT that's reserving them, here's how you still let WinNAT do it's job but get a usable chunk of your ports back.
REM THIS COMMAND LISTS ALL RESERVED PORTRANGES FOR TCP (can be changed to ipv6 and/or udp)
netsh interface ipv4 show excludedportrange protocol=tcp
REM THIS COMMAND SETS IT TO BE DYNAMIC AND THE FUCK OUT OF ANY DEVELOPER'S WAY
REM (Run in Admin powershell)
netsh int ipv4 set dynamic tcp start=49152 num=16384
REM Fucking hell microsoft...
REM Here for original fix https://github.com/docker/for-win/issues/3171#issuecomment-554587817
REM Restart the WinNAT service (Run in Admin powershell)
net stop winnat
net start winnat
