Configure dnsmasq as IPv6 nameserver but let router do routing (and maybe IP address assignment)












1















Suggestions welcome!



I'm moving DHCP and DNS services from a combined router (192.168.0.1) to a separate system (running on 192.168.0.2) with dnsmasq. I want the first system to be the default route and the second system to handle dns. How should I configure dnsmasq for this?



So far it works fine for IPv4 all system gets addresses and the correct name server. But when inspecting IPv6 settings in the terminal I see it is not using my internal DNS, but is using the IPv6 addresses of the ISP's DNS servers.



How should I configure so the IPv6 addresses are routed via the router and the name-server lookup is directed to my local name-server. The configuration options for v6 and examples I have found so far seem to only be suitable if both router and name-server are running the same machine.



Any suggestions pointing me in the right direction will be appreciated



Config:



$ grep -v '^#' <dnsmasq.conf |uniq
server=127.0.0.1#5053
bind-interfaces
dhcp-range=192.168.0.50,192.168.0.150,12h
dhcp-option=3,192.168.0.1
dhcp-option=42,0.0.0.0


version:



$ dnsmasq -v

edit:
resolv.conf (but this is not where I see the IPv6 name-server - they can be seen in on an Android device on the network)



$ cat /etc/resolv.conf 
# nameserver 1.1.1.1
nameserver 192.168.0.2

$ sudo netstat -l -u -p -n

  • 1. The distribution is some xenisal (16.04.5 ?) for arm based distribution. 2 maybe - not sure what I am looking for 4 Yes but I only want to change the name server in the IPv6 case
