I've been using Kerio Personal Firewall v2.1.5 (not the later Kerio's) all the way back to when it was called Tiny Firewall. I absolutely love it. I've tried many over the years and have come away disappointed after being spoiled by such a wonderful product. I'm looking for something similar to Kerio but perhaps a bit more hardened. Kerio has been EOL for ages. It must be as configurable as KPF. That it to say; it must alert me to each and every connection attempt, to define what program making the connection, what IP(s), port number, what type...UDP, TCP or ICMP and type of ICMP, incoming, outgoing or both directions, etc. Most of these must be definable in the firewall alert. It always can't be bloated. KPF is 3 files, totally 980 KB (not counting the help file). I might have asked this before and not looking for miracles just anything close and nothing bloated but I don't expect miracles like 980 KB. .
