Configure F5 GTM to forward DNS query

Hello Stanislas,

If I just want to forward specific queries towards certain servers, what is the easiest to do?

In bind this would look like

zone "site1.F5.com" {
  type forward;
  forward only;
  forwarders {1.1.1.1 ; 2.2.2.2; };
};
zone "site353.example.com" {
  type forward;
  forward only;
  forwarders {3.3.3.3 ; 5.5.4.4; };
};
zone "urgent911.example.net" {
  type forward;
  forward only;
  forwarders {3.3.4.4 ; 4.4.1.1; };
};

Of course without too much interference on other config (DNS express, other GSLB, ...)

Or to ask the question different, you mention "◦if no pool member is available and fallback method is "return to DNS" the request is released to DNS server" => to which server it is released ...

thanks in advance for your answer.
