I have used kerio PF before 2.1.5 , but it got abandoned, and their new version is really ...not good. LNS looks and feels much much better I am trying it now on Windows xp hone SP2. I got issue with home network (yeah yeah I saw a lot of posts about it) - file\printer sharing etc. I've read and tried advices about importing sharing.ie rules, about applying NAVRegPatch, about enabling NetBIOS or 445. Nothing worked so far. I guess I need to start from the beginning - understanding of the LNS So, I have basic question: 1. What service/driver performs firewalling? I installed LNS with option - "NOT to start automatically when Windows starts." but as soon as system rebooted to complete installation - file sharing stops working. As soon as LNS unistalled with system reboot files sharing works again. 2. Is there way to tell from the log if rule applied to stop packet or just reported this packet?
