Configuring a domain slave to look up subdomain hosts

[Chris Buxton]

Sorry, my mistake. Apparently, it needs to be overridden (disabled) in each affected zone, not just at the domain apex.

If you leave out the stub zones entirely and disable forwarding in the parent zones, it should work. That way, the server is simply following delegations, rather than relying on stub zones.

I have it on in global options because we don’t let internal name servers go to the root; they forward to our dmz name server for internet lookups.

I thought a stub zone would facilitate this by giving my server the lookup information it needed to do this. Apparently this is not the case. Even though it receives a db file with the NS and SOA information for the subdomain, it is ignoring it. Forwarding works. Being a slave for the subdomain works. Stub zone doesn’t work.
