I currently use TinyWall Firewall, it works very well, it’s small/portable, no complaints I even donated to the Dev but I would really prefer open source, also it needs to be user friendly like TinyWall so my non-tech family members can/will use it like they do with TinyWall.
What’s wrong with the built in windows firewall? It works well, has a GUI to add rules, etc… You don’t even need to touch it on a default setup for most people.
Because it’s awful to use, counter-intuitive, and fucking breaks network connectivity all the time by switching private networks to public on a whim.
Fuck that piece of shit for that reason alone. I’ve seen it fuck domain controllers doing this, when “supposedly” it can’t do this on a DC. Know what happens then? I can’t RDP to the server from it’s own local network.
This is such a problem we run a powershell script on a schedule to ensure the connections remain private.
