I'm in love!
First, a little background: I have been the firewall administrator, and now CSO, of a small software company (also providing firewall services to many customers) for a pretty good number of years. I've worked exensively with Linux iptables/netfilter, Symantec Enterprise Firewall (formarly Axent's Raptor), Secure Computing Sidewinder G2, and a bit with Cisco PIX and Checkpoint NG. At home, I've been using Linux iptables/netfilter with OpenSWAN, and in recent years, Shorewall, with a brief stint or two with m0n0wall.
I recently found out about pfSense after a troublesome Debian 4.0 upgrade on my home firewall left me unable to connect to work via my IPSec tunnels. I then tried m0n0wall again, but again had troubles with FTP uploads not working. I saw a post on the m0n0wall forums about pfSense and decided to give it a try. I LOVE IT! This is fantastic! I just wanted to say, "Thank you," and "Fantastic Job!" Not only do FTP uploads work, but pfSense is a fantastic system in general.
Glad to hear it. ;D
