Is there a proper way to reset firewall rules in FreeBSD8.0 ? I just discovered that if one is remotely logged in and makes a change in the firewall rules, it is a disastor to do something like sh /etc/[firewall_rules_script] 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 ipfw list 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.
