Using hidden config dhcpd/(if)/domain (taken from FAQ) the DHCP works fine -
The computer receives the configuered (interface specific) domain from DHCP.
Now if one activates register DHCP with DNS on DNS Forwarder page, the result
is not as expected.
Sample to make it clear:
Host "box" gets foo.example.com as its domain.
But you have to ping box.example.com instead of the expected
box.foo.example.com. With other words ping box.foo.example.com doesn't work.
Therefore the DNS registeres the host on the same domain as m0n0 is, but not -
as expected - on the subnet specific domain.
Hope I made clear what the problem is..
