named. Yes, you are correct, I found it a few minutes ago. I was not passing local traffic to the Internet. Funny though, named runs on the firewall machine and I was allowing its traffic. I monitored both interfaces with tcpdump and there was no traffic except for the occasional netbios stuff from the Windows machines. They didn't seem to trigger the messages though. Anyway --- all messages have ceased with the proper outgoing rules and stateful rules. Why does the default SIMPLE firewall in /etc/rc.firewall configure in such a way as to cause these messages to flood the logs?
