Thanks for the link! At the moment i cant see the big difference between our configs. But maybe it is some more basicly? My ppp0 interface has the only routeable IPv6-address, the p3p1-Interface doesnt. Does it need a routeable address? If yes, which one should it be (according to ppp0)?

Re: [Dnsmasq-discuss] Dnsmasq and bond0
Hi, This looks like a bonding issue rather than a dnsmasq issue. What happens when you remove the bonding config on the host, down all interfaces but one, and unplug all interfaces but one on to the switch? If that fixes it, then you have a bonding config issue on either the host or switch side. In order to troubleshoot that, you need cat /proc/net/bonding/bond0 as well as the port channel and interface configs off the switch. If it's a Cisco, then it's something like sh run int port-channelN as well as each interface in the port-channel sh run int GigabitEthernetX/Y/Z. Not sure that everyone on this list is interested in a bonding issue, so I'm happy to help troubleshoot it off list.
