Different forwarder for certain response ip (result ip )

[Alberto Colosi]

port 53 is only open directed to forwarders

as I read , you think to use different forwarders so , port 53 should be open to all IP             ,   right ?


I think u should read how DNS works, TLD and so on


simply drop forwarders only use TLD

Wow . I love active community .

Actually my situation is a bit strange . But as explanation i can say that
our upstream provider do dns manipulation on normal ports 53 tcp/udp (please
don't ask why). We may not use vpn or tunnels . The only way is using
alternate ports as forwarders.

But i can not use alternate ports as my main forwarders because if so , then
upstream provider may be aware of that and manipulate them also . So if i
could use them only for certain requests then everything may work fine.

Note:My BIND dns server is caching server .
