I have setup conditional DNS forwarding for certain subdomains but it is behaving in a way that I think is unexpected.

This is what I have setup. -> ->

Now if anything is going to it does forward that dns request to However, if there is a domain then it does not forward to instead nslookup says that it did not get a response.

However, if I setup another conditional domain rule that says: ->

then does resolve.

Is this by design? I thought it would act like a wildcard but it doesn't.
