@johnpoz No doubt. I did at one point simply because I was lazy and didn't trust comcast to do the right thing if I swapped out a wrt54g. In my case, it actually saved me because my sg2440 fell victim to the red led of death, so moved one cable, rebooted wifes stuff and minimal downtime.
(that sg2440 was fixed under RMA and has been working fine, but I've got a 5100 on order just in case).
I always liked seeing the rules as applied (pf user before pfSense), that command helps me figure out exactly what is going on, you can mentally walk a packet flow.
