  1. I’ve used pfSense for about 5 years now, and I’ll go on the record to say that this is my favorite router platform by far. I tested several different platforms in the lead up to choosing pfSense, but none of the others met my needs so completely.

    Particularly, I really love the “pfBlocker” & “Snort” add-on packages. Those two packages combined have reduced the threat level to my network by an extreme degree and allow to me to stop threats before they grow into a full blown problem.

    Also, the NAT forwarder rules tables are some of the best I’ve ever used because of the automatic and simultaneous generation of firewall rules that allow an administrator to perform very granular shaping of their network edge security to a degree seldom found outside of Cisco’s offerings… yet not requiring near the degree of training to understand.
