Hi, I extended dnsmasq with a MySQL backend to a) get reserved IPs from a DB table b) update lease time in a DB table It's a first try so use it with care. I tested it for 3 days with ca. 50 clients (leasetime 2 hours) without any problems. Here's the link: http://www.0xcc.de/dnsmasq-2.20-mysql-patch.tgz Cheers, Marko
