Ok, everyone who has NEVER ever made that mistake (or locked themself out with a firewall rule, accidentally putting it into effect before testing) raise their hand. :)
Yes, that would be me. But someone taught me a great trick...the "at" command. So, just before you blow away your access with changes to ipfw, do this:
echo "ipfw add 1 pass all from any to any" at now +10 minutes
Then if all goes OK, use atq to remove the queue item. If not, wait 10 minutes...
