I've been tinkering with pfsense 2.0.1. Previously I had spent considerable time building my own nanobsd 9.0 images and configuring pf manually from the CLI using pf.conf. I noticed this morning that pfsense has an option to create a "queue" rule on the "Floating Rule" page. This creates a "match" rule instead of the standard "block" or "pass" rule in pf.conf.
As far as I understood it, FreeBSD 9.0 is using pf 4.5, which does not include the "match" rule syntax. Yet, pfsense 2.0.1, which is based on FreeBSD 8.1, does have the "match" rules? Is this a pfsense specific patch? Is pfsense using a different version of pf?
