dhcp Unable to add forward map from..connection refused

[tangonights at yahoo.it]

hello everybody..

I was playing on my gentoo box: a couple of virtual machines, client and 
dhcp/bind server.
both services do their job - separately. I tried to configure the dynamic 
update, but my log said (weird things *highlighted):

I guess it was something wrong with my bind configuration, but google has not 
been my friend this time :-)

I post also my bind config files:

	notify yes;

and, just in case, my dhcpd.conf too:

	zone 1.168.192.in-addr.arpa. {

	}
}


Could somebody tell me why that 'connection refused' and where am I wrong?

Thanks,
Stefano.
