alternative url not working.

[kilburn]

Try with:

Code:

*.admin.server1

The error is that, according to the wikipedia entry about DNS wildcards, "vuXXXX.admin.server1.domain.tld" should resolve correctly if you have an "*.server1.domain.tld" wildcard entry (see the "foo.bar.example." example query in the article).

As you've said, your provider's DNS server is not resolving this query as it should, so you'll have to try to force it into doing so. The above way is the only one I can think of right now...
