Filseclab Personal Firewall Professional Edition
Full user review
"Great for newbies, not great for personalising."
Gorgeous interface. Popups are easily stilled once you've allowed/blocked the program.
Can't tailor blocks/allows by a range of IP addresses or ports. Apparently setting specific "safe/danger zones" by a range of IPs doesn't allow or prohibit a program from being allowed/disallowed.
This isn't a personal firewall; typically the "personal" means you can tailor it to your personal computer's needs. Since this one only allows exceptions to be set up for one specific IP address or port, I do not have time to set up 256 exceptions for one program's need of the x.y.z.0-x.y.z.255 addresses (not even mentioning which ports I'm okay with it using)! I put in my range as a "safe" zone, and keyed up the exception to allow my program to access all safe zones... yet it constantly popped up with asking for an exception. I don't want all my programs just allowed to access any IP address; I know what I'm doing and I know what I want my programs to access (or not to), so only being able to entirely allow or block a specific program is about as useful as no firewall whatsoever.
