I assure you that I didn't have firewall_enable="YES" set and yet the
firewall was turned on once my system came back from reboot. Stock 4.6.2
install, security branch cvsup. I am looking at rc.* this very moment.

If I had enabled the firewall in rc.conf, I would richly deserve
whatever punishment I got. :)

One I finally got a hold of a guy on-site, his trying to use ping on the
server make it pretty obvious that that firewall was active. He added an
entry to rc.local that starts up the firewall with a more lenient rule
set, but I will look at /etc/defaults/rc.conf to figure out how IPFW is
supposed to be started up from rc.conf.

I swear that the firewall came up without any changes to rc.conf,
otherwise I wouldn't have emailed you folks in the first place...
