I have no NAT.
I do a simple test and set in DNS a new A record so I have test.domain.tld.
Under my official NAmeserver there is a wildcard entry *.domain.tld and it is resolved successfull.
but when I point the browser to the new host record test.domain.tld then I get the shared IP error.
So what is going wrong? I can not browse to another A record nor have access to host.thirdlevel.domain.tld.
Can someone help?
