<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I setup my environment with “split horizon” logic, using two Auth servers, one for public zones and another one for private zones, all works correctly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now I want internal clients resolve some public zones with private ips, I know that I can duplicate the zone from public auth server to private auth server changing ip addresses but this way I need to maintain the same zone on both server
with different resolution, example:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="http://www.mycompany.net">www.mycompany.net</a> -> 1.1.1.1 (public resolution)<o:p></o:p></p>
<p class="MsoNormal"><a href="http://www.mycompany.net">www.mycompany.net</a> -> 192.168.1.1 (private resolution)<br>
<br>
I have the zone mycompany.net on both auth servers (public and private) and the record “www” is resolved with “1.1.1.1” on public auth server and “192.168.1.1” on the private one.<o:p></o:p></p>
<p class="MsoNormal">Assuming I need to add a record “<a href="ftp://ftp.mycompany.net">ftp.mycompany.net</a>” only with public resolution i need to configure the record also on the internal auth with the same public ip, otherwise internal client will receive
an NXDOMAIN.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here my question:<br>
Can I manage on dnsdist or pdnsRecursor this issue? I think something like that:<o:p></o:p></p>
<p class="MsoNormal"><br>
1. Private client ask private dns to resolve <a href="ftp://ftp.mycompany.net">ftp.mycompany.net</a><o:p></o:p></p>
<p class="MsoNormal">2. Private dns try to resolve it but the record is not present and generate an NXDOMAIN<o:p></o:p></p>
<p class="MsoNormal">3. “someone?” intercept this NXDOMAIN and forward the same request to the public dns<o:p></o:p></p>
<p class="MsoNormal">4. private client get the answer<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If this is possible, maybe with lua, I can add to the zone in the private dns only records that overrides the public ones, without to manage full zone on both dns.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Someone have some suggestions?<br>
<br>
Hope my request is clear!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
