Re: [Pdns-users] Forward client request

2019-11-12 Thread Thomas Mieslinger 

If you are familiar with policy based routing or multiple vrfs and
running multiple pdns_recursor instances you could create two (or more)
pdns_recursor services and configure the routing to send the dns
requests to the desired recursor.

Is there any example on lua?

Hi "Mendisobal",

For this kind of forwarding we recommend using dnsdist. It is also freely
available. The PowerDNS Recursor itself has a very hard time doing stuff
like this.

Good luck!

If you're forwarding client requests programmatically, then you probably 
would be better off using dnsdist (and there's a different mailing list 
 for that)


I don't know if this is relevant to your situation, but there is also 
something related called "edns client subnet".  This allows an 
*authoritative* server to return different responses to the *recursor*, 
depending on the source subnet of the *client* which made the query to 
the recursor.


HTH,

Brian.
