Re: [Dnsmasq-discuss] could not bind dnsmasq to mutiple interfaces with same ip-address ... success report
Hi Simon, now i changed every interface-line to a listen-address-line. All is working just fine :-D Including DHCP and DNS. Perfect. Thank you !

More than one interface with the same address is causing confusion. That seems a very strange thing to do, but commenting out bond4 and bond5 won't cause any problems, dnsmasq will still be listening on 91.205.12.0 Unless there's a good reason, removing bind-interfaces will make this configuration much easier to use.

Michael Rack wrote: I have in mind, that dnsmasq does not handle DHCP Requests if there is a ip-address configured. I switched then to bind-interfaces... you can use --interface without --bind-interfaces But why is the same config not working as before? DNSMAQ did not had problems on my old server with this configuration. Different versions of dnsmasq? I only looked at the latest code to see how it would behave with repeated IP addresses, older code may break differently. Cheers, Simon.

But without dnsmasq starts without problems, so the interface status does not matter. The Interface is really up, as you can see.
