Is there a proper way to reset firewall rules in
FreeBSD8.0 ? I just discovered that if one is remotely logged

One could do that in FreeBSD6.x. When the rules flushed,
you lost your connection, but the script continued to execute
and the new rules were in effect immediately. Trying this same
reload in FreeBSD8.0, I knew something was horribly wrong when
everything just locked up. I logged on to a local console and ran
It had stopped right after the flush.
Doing the same command from a local or even a serial
console works fine and the new rules are installed.
Thanks and maybe I have been using the wrong technique
for reloading firewall rules all along.
