Specifically, when I use my wifi, I cannot get internet programs to work. Example, accessing ACT from microsoft (paid subscription). If I switch to tether my iPhone instead of wifi it works perfectly. If I go to any other wifi it works perfectly. Only when I'm using wifi on parallels. Everything else works fine on Mac and parallels. Happenes on both catalina and Big sur. Routers, modems, up to date products have been checked. Narrowed down to firewall?? One time removing firewall allowed it to work but when rebooted when to same behavior
