BIND DNS question - only forward certain dns requests ?

Posted on 2007-03-27
Last Modified: 2013-12-23

We are implementing a fail-over / load balancing solution based on Radware AppDirector.

The Radware AppDirector will redirect the users by acting as a DNS server and "feeding" the visitor the correct DNS record.

Problem: we want the Radware to only handle dns for two dns records ( and ), BUT NOT FOR THE OTHER 30 dns records in our public dns zone.

I know Windows 2003 has something called "conditional forwarding".
How can we solve this using BIND ? Forwarding only allows us to forward a complete subdomain ? Other possibilities ???

You could add a local zone to BIND as and add the two records you require beneath it. It wouldn't forward requests for any other records within

Hi Chris,

It's the Radware that will be handling dns requests for these two records.

The other records that will be managed by BIND.

The Radware has very basic dns capabilities ( no zone creation, ... )

It's a pain, but you could fill the Hosts file with the other 30.

Unfortunately conditional forwarders in BIND are also a type of zone. e.g.:

zone "" IN
      type forward;
      forwarders {a.b.c.d; w.x.y.z;};

Have you considered making a sub domain, and delegating DNS for that sub domain to  Radware?

so Bind will handle
and will pass to Radware for load balancing.

Just a thought.

Yes. I was considering this as well, but it just doesn't feel like the right way to go. Nevertheless, if this is the only low-maintenance solution ...

I was just wondering if this has any disadvantages ( search engine bots, ... ? )

It depends what the server does. search engines and bots can't use a Hosts file, and from what you've written I hadn't imagined the server hosting public DNS services.
