What you want to do is NOT list your local system as an official secondary. This way no queries from the net will go to your local server. You can still have the local functionality by having it still being a secondary. Your local machines can ask it about your domain, and it will answer since it knows its a secondary and thus authoritative for the domain. --- David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
