[Dnsmasq-discuss] Fritzbox and frequent router advertisments

[Robert M. Albrecht]

Hi,

I using a Fritzbox and a dualstack internet connection (Deutsche Telekom).

Fritzbox is providing router advertisments with rfc5006 dns.
Fritzbopx is running stateless dhcpv6 with IA_P but no IA_NA.

I have running dnsmasq 2.72 on Fedora 21.

My Mac and Linux boxes are happy, but my Windows machines are very unhappy.

VPN tunnels on these Windows machines are extremly unrealiable, when 
dnsmasq is running. If I stop dnsmasq, everything is ok.

In my logs I see lot's of these, and I'm unsure if this might be the 
problem.

Looks like dnsmasq is frequently contructing and deconstructing the 
network interface ?

Avahi seems to think the interface is going up and down. But why ? The 
address does not change ?
