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.
Do people really run zenarmour, snort or suricate on their desktop?
Feels like a network firewall thing to do DPI for the whole house, instead of a per-machine thing.
