We are not using quantum yet, but we do use a default gateway that is different the the local server IP. The way we do it is to add the configfile "/etc/nova/dnsmasq-nova.conf" with "dhcp-option:tag:br1099,option:route,10.81.99.1" in the file.
I hope this helps, let me know how it goes as I am going to be looking into quantum/neutron to do networking soon.
