Hello,
I'm running a N66U with Merlin 378.55. I've set the router to handle IPv6 from the ISP and I have a few scripts to bring up a ULA address for internal traffic (such as dns, or finding a device when ipv6 range changes).
Assigning the address on the router works alright, but there is some strangeness. Ideally, I need the address setup right before dnsmasq is activated - since dnsmasq will send out RA/DHCPv6 for all address configured on the interface its using (br0).
I have this combination script setup:
dhcpc-event:
And dnsmasq.postconf:
This setups the configuration as expected (although for some reason the ip address doesn't come up or stick).
However on my Windows systems the DNS Server is listed as my ISP's assigned IPv6 Range and the ip of the router.
How do I get the router to stop assigning its self as a dns server and just use the provided ULA address for DNS Lookups?
Thanks. Also I am happy to provide additional configuration information as needed.
