[Dnsmasq-discuss] IPv6 on OpenWRT

[Alec Robertson]

Hi all,

I am using dnsmasq on OpenWRT and I have configured the DHCPv6 server and
it is working well with the clients connected to the router. However, the
DNS is not working; IPv6 requests are not successful.

The clients are given the router’s IP for DNS, like they are with IPv4 but
the DNS is not working. How do I configure the DNS servers on dnsmasq
correctly? I am using a 6in4 tunnel via Hurricane Electric.

Hi Alec,

I would check the following:

1) Is your router listening on an IPv6 like address, like an unspecified
::?
2) Is your client trying to reach that address and port? You can check
that using tcpdump.
3) Are you using an IPv6 upstream DNS server? You can check Googles DNS
server, I use it.
4) Check the /etc/hosts and see if it has some entry like: localhost6 ::1.
5) Check your router's connectivity with the IPv6 DNS server (ping6).

I hope that was useful.
