I've used the same firewall through xp, 7 and now 10. It lets me block ips, ip ranges, exes, dlls and is light-wieght, stand-alone and doesn't add a 'suite' of 'features'...it's just a firewall.
But, It doesn't let Wireguard work. I have to switch it to 'Allow Traffic' and Wireguard connects instantly. Haven't discovered any way to configure it that allows Wireguard to connect (and I know this firewall pretty well after all these years).
So I need a new one since Mullvad is sunsetting OpenVPN and Wireguard will be our only choice. A majority of firewalls out there use the Windows API (WFP filters) or just act as a 'front-end' to Windows Firewall. There are a few that 'roll their own' API and get away from dependence on Windows, but most of those have become bloated 'suites' of subscription services, not what i'm looking for.
Simplewall and TinyFirewall are both no longer maintained and I have no idea if they'll let Wireguard work.
Fort Firewall requires us to redirect DNS on Mullvad and Windows networking to localhost and admits Wireguard is 'iffy', if it works at all.
So what's my options? Anybody know a firewall that's not Windows that works for Wireguard?
