DNSSEC and forward zone

[David Carvalho]

Anyway, It is working using your suggestion. Apparently everything is also fine  from the outside.

But I’ll have to check Petr Špaček post and study more.

Thanks!

David

Hi David,

 

You can disable validation on one or more domains using "validate-except" - https://bind9.readthedocs.io/en/latest/reference.html#namedconf-statement-validate-except

 

Thank you,

Hello guys

Asking for your help, again.

 

So after setting up DNSSEC I’ve found I couldn’t reach some internal sites on my top domain, served by internal DNS servers

There’s no need in hiding domains as my e-mail is shown here.

 

Top domain

	
	


 

 




ubi.pt <http://ubi.pt>  (external DNS Servers authoritative)

 

          Internal DNS servers (windows, Active directory - Recursive)

     <http://Internalsite1.ubi.pt> Internalsite1.ubi.pt

                    <http://Internalsite2.ubi.pt> Internalsite2.ubi.pt

                …

 

 

di.ubi.pt <http://di.ubi.pt>  

(both authoritative and recursive for my networks)

 

Previously I had the following to get internal sites resolved, but now it seems it is completely discarded by dnssec.

 

zone "ubi.pt <http://ubi.pt> " IN {

        type forward;

        forwarders { 192.168.100.1; 192.168.100.2; };

}

 

Is there any configuration to allow me  to be able to access internal sites served by internal dns servers, I guess not using DNSSEC?

Can this only be accomplished by adding these entries to my parent domain?

Thanks!

 

Kind regards

David Carvalho
