I generally do not comment on product releases, but this is a special case. pfSense is a software firewall. It is like IPCop, Endian, M0n0wall etc., just…. better. I've been testing their BETA versions for the 2.0 branch for the better part of the past 2 years on no less than 10 different sites, and have been mightily impressed with the power and user friendliness.
Go get it from here.
