UDP packet/DNS server

Hello Nanog, I am trying get zone trasfer from a host, but it seems that because of firewals?, I can not get any record. They acknowelged that there is a host behind the firewalls but they claim it should not affect it. (I don't believe it.) But I don't know how to check/prove that if certain host can receive/send an UDP packet.
