Subject Re: Configure individual DNS Servers for isolated Network
Date Wed, 13 Mar 2019 18:56:58 GMT
Hey Dag,

thanks a lot for the swift answer!

Yes we where aware of the possiblity to change the VRs DNSMasq
configuration to achieve the desired effect but did not like the
solution, because we did not like it to be non-persistent.

I was thinking about manipulating the database, too. Good to hear you
did not succeed with this approach. So I will not dig deeper into that.

I discuss the options with my collegue!

Wishing you a nice evening!

Greetings,

Melanie
