Many of the firewall solutions are IP and Port based but escpecially for a newbie that is not easy to do. This is why an easy to use and especially easy to understand firewall is a valuable addition to the repos.
Application level firewalls are a great newbie conform alternative to IPxPort based firewalls.
OpenSnitch is available from the AUR but it throws hundreds of errors (int is being compared with unsigned int?!) when I try to built it with pamac. The app does not end up starting, only the system tray icon is there and through it I can open the stats window but that's all.
FirePrompt is only available as a .deb package.
I should add that both of these programs are not that mature yet. At least OpenSnitch seems to be quite early in development and quite buggy although the installation problems are probably related to manjaro I guess?
If you end up not liking the idea of maintaining unmatured apps, do I have a realistic chance when I request these again in the future when they run better?
Thank you anyway!
