	What makes you think the update requests are going to 127.0.0.1?
	The requests go the address associated with the MNAME in the SOA
	record.

	lyon.atempo.dk isn't delegated in the Internet.  You need to make
	sure ALL the nameservers listed in resolv.conf can see the SOA
	record for lyon.atempo.dk.

	I would be using "allow-update { localhost; };" or preferably
	a TSIG to secure the update request.  The "localhost" acl has
	all the addresses of the nameserver in it.
