This one seems to be a good firewall in my opinion. It has a learning feature to help. It has a real logging feature . You can access the rules right in the Windows firewall settings if needed. No annoying pop-ups. It s purely free ,no registration and such. I think i prefer this over direct manual control of build in Windows firewall as there are cases with programs that you can t make proper rules for.With this one you can identify exactly the executables and tweak the ports needed. I congratulate the guy that made it.
