I have been using Kerio Personal Firewall for quite some time. Many times I have been forced to uninstall and reinstall the application due to unknown problems, but this latest one is a real winner. Put simply, if KPF is enabled, NO network activity works. There is nothing in the configuration which could explain this. I removed all networks and application records, but it still would not work. The only way to get any communication through is to disable KPF. Then everything works fine.
Have they decided to just sabotage the free version once in a while so that people might resort to paying for the pro version just to get support on the product? If so, it hasn't worked on me. I have removed it. I think this will be the last chance I give the software. I realize it is free and therefore I should not expect the utmost in quality or support, but for it to simply cease functioning from time to time with no explanation as to why, and no significant changes made to the system to explain it, I just don't have any faith in the software anymore. It makes me suspect that it is being crippled as a "buying incentive" but for me this is only incentive to look for a better product.
Anyone else with similar experience? If not, can anyone recommend something? I need to protect incoming AND outgoing connection attempts. I don't really need any of the other features, just connection detection and prevention.
