[Dnsmasq-discuss] No dynamic addresses to unknown hosts

[ms at webstollen.de]

Hi,

when I try to get a dynamic IP address via DHCP, dnsmasq outputs "no 
address available" (see below). When I do the same from a machine whose 
MAC address is registered in dnsmasq.conf, then dnsmasq can give me an 
IP address (see below). I'm using virtual VLAN interfaces eth0.3, eth0.4 
and eth0.6, but I think that's not the problem because dnsmasq receives 
DHCPDISCOVER requests on these interfaces. So, how can I manage sending 
IP addresses to unregistered hosts?

You can see `dnsmasq -d` and dnsmasq.conf below:
