Kerio personal firewall is good and free (note lowercase free)
Norton personal firewall performs far far better at blocking portscans (tested with
www.grc.com, www.pcflank.com and some scanners I downloaded) than zone alarm does. I know scanning isnt the only thing it should be good at (eg should also stop plain wrong packets) but i cant be bothered testing for other stuff (and i wouldnt know what i was doing) and if your on a dsl modem your probably mainly worried about kiddies with scanners anyway. That said the "logging" feature in norton is annoying and it is expensive. I still believe for client end windows comps its good though.
However! Obviously its a win program and nothing could really secure a dam with taht many holes... wouldnt it be nice if there was some way to put a dedicated firewall on a cool OS "in between" your computer and your isp? wouldnt it be even better if the cost of the old comp for that dedicated hardware firewall was cheaper than most win firewall apps?
heres the ultimate solution! smoothwall!
this puppy comes with a pretty full on firewall, AND it masquerades your computers behind it AND its been hardened up for security AND you dont need to waste your desktops CPU cycles on a firewall ap AND the cost of the (not necessarily fast) computer to run it on would be no more than $50 AUS ($25 US) AND theres no need to waste desktop box hdd space or RAM on a firewall app AND with a hub you can have one firewall managing multiple comps so you dont need to mantain seperate firewalls on multiple comps at once! AND if your "interested in learning" like you said then seeing the output of iptables -L will help a lot as will reading an iptables script
BUT WAIT! THERES MORE!
AND its Free Software!!! (in BOTH terms!)
Ah CRAP! Ignore alll the above just noticed that theyre still working on DHCP... :rolleyes: :rolleyes: :rolleyes:
sorry - AND you can wait till they add dhcp support!
edit : ha ha ha! I was wrong! Smoothwall still "0WnZ j00 4r$3" 8-)
