Well , Megamaced : would you like to try lavasoft ? I can let you for free.
I just finished up testing the new comodo,and I must say that the older version
is beter. With this new version it would not startup right. Now Kerio has been around a long time,I have there very first version,They make a real good firewall as well, but some of there versions are Quite buggy. There first version 2.1.4
was real good,In fact it is the same firewall as Tiny firewall, Tiny and kerio back then was the same,,, Anyway I like Sygate as well it is one of the best and most stable firewalls made. I would just use version 5.5 standard or pro version.
You just have to get it when it was 100% Sygate, and not the version they use now,since they where bought out.. Anyway send me a private email if you what to try Lavasoft....
