Just a warning to anyone who is considering using the 2.1.x series since 2.2 is rumoured (I stress that word highly) to be out soon. If you use IP-Masqing it appears that the 2.1.x kernels break ipfwadm. With a broken ipfwadm it isn't possible to add/remove IP-Masqing rules like "normal." There may have been another way, but I did this on my production machine (silly, I know) and just simply reverted back to my 2.0.x series kernel.
