Davidd`s site 'wilders.org' is a darn good site.
Security for all and from someone who knows what he is talking about.

Hi. Try www.grc.com and go to his firewall page - some fantastic information there on personal versions.

Basically a firewall is a packet filter which examines incoming and outgoing data and destinations and blocks according to rules you've set. Works similar to a proxy, but not as efficiently.

A technical but readable discussion on the differences can be found on a local site: http://www.soho-systems.co.nz/

A great free firewall is ZoneAlarm (personal edition) available from www.Zonelabs.com
