The following instructions for CeroWRT worked for me with Windows 7
clients. I set it so that addresses are assigned via SLAAC with radvd
doing announcements, and DNS servers etc. are announced over DHCPv6.
# opkg update
# opkg remove dnsmasq
# opkg install --force-reinstall dnsmasq-dhcpv6
Insert several lines into /etc/dnsmasq.conf describing the dhcp ranges:
dhcp-range=se00,</64 goes here>, ra-stateless, ra-names
# /etc/init.d/dnsmasq restart
At this point, you'll probably get the router's local IPv6 addresses
as DNS servers. This is fine except that named is not configured to
accept IPv6 traffic. This should not be relevant for 3.3.8-21 since
that uses dnsmasq only, but for 3.3.8-17 and earlier, edit
/etc/chroot/named/etc/bind/conf/acls.local.conf and add in your IPv6
prefix, then "killall -HUP named" to update BIND.
We could replace radvd entirely at this point and use "enable-ra" in
dnsmasq.conf, but I think radvd gives us more options. For
DHCPv6-only address assignment, you can remove the "ra-stateless,
ra-names" parts in our new dhcp-range lines, and set "AdvManagedFlag
on" in radvd. I can't imagine OS X requiring that level of attention
though to get an IPv6 address; merely using "AdvOtherConfigFlag off"
in radvd.conf ought to do it.
