[Dnsmasq-discuss] IPv6: listen-address= versus interface=

[Gene Czarcinski]

In my recent testing, I believe I may have discovered a small problem 
(bug?) related to IPv6.

For IPv4, if you specify listen-address= or interface=, both the name 
and dhcp functions work.  For IPv6, if you specify interface=, again 
both the name and dhcp6 functions work (dnsmasq responds).

However, for IPv6, if you specify listen-address=, the name function 
works but not the dhcp6.  That is, the client of the service issues the 
dhcpv6 requests but there is no response from dnsmasq.  Changing to 
interface= immediately got everything working.

I suspect this is not working as intended.

My testing was all done virtually with qemu/kvm/libvirt virtualization 
on Fedora 17.
