<p>dnsmasq supports setting parameters such as the gateway IP and other settings based on tag. I have run a patched version of nova-network in the Diablo time that used the network DB label field as the network tag in dnsmasq. This then allows you to set custom configs by modifying the dnsmasq.conf file. This was done with VLANmanager.</p>
<p>Thanks</p>
