The master/slave udp chatter is just a source that triggers this error. I couldn't reproduce the message using something like nc -u, but somebody more familiar with this may be able to. >How-To-Repeat: Firewall config ================ Minimum rules method: -------- Load the firewall as a kernel modue #kldload ipfw Add a keep-state UDP rule to the firewall ipfw add allow udp from me to any keep-state Alternate method -------- set the following rc.conf variables to use somewhat more complex built-in "workstation" rule set firewall_enable="yes" firewall_type="workstation" Named config ============ edit name.conf Add slave zones. Master server does not need to allow access for this to be triggered, just the slave trying to connect is enough. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
