Hi Simon, I find myself confused by the use of the constructor option for building DHCPv6 address ranges.
edited dnsmasq.conf file: enable-ra dhcp-range=tag:br0,::1, ::FFFF, constructor:br0, ra-names, 12h Now on my Tomato based router this picks up then (tunnelled) ipv6 LAN address on the BR0 interface, which happens to be ISP_PREFIX::1 It builds a range ISP_PREFIX::1 -> ISP_PREFIX::FFFF and all is well. However, others do not have a nice neat '::1' they have (presumably because it's been delegated to them by their ISP) something like ISP_PREFIX::DEAD:BEEF:F00D. Now there are two problems as I see it with this: 1) I now need to specify my starting IP address range as DEAD:BEEF:F00D otherwise dnsmasq doesn't find the prefix and doesn't serve an IPv6 addresses at all. In which case why am I even bothering to tell it the interface in the constructor? 2) The range parameter (:FFFF) implies I can define a range from DEAD:BEEF:F00D to DEAD:BEEF:FFFF only with nothing lower than F00D. I'm sure I'm being stupid here, please educate me.... again :-) Kevin
