Windows – Unable to do forwarding in BIND DNS

bindforwardingwindowswindows-server-2003

I have BIND working on Windows Server 2003. I want to forward my queries to another server. Recursion is working but forwarding is not working. Can you guide me to set it up? I have given the following in the options:

options { 
       directory "c:\named\zones"; 
       allow-transfer { none; }; 
       forward only; 
       forwarders { 8.8.8.8 ; }; 
       recursion no;
};

Is the format for forwarding correct in the above.

If not what is the format. Am i to give any port number in the forwarders line? Does forwarding have any particular port number?

Thank You in advance….

Recursion should not be working, as you have "recursion no;".

options {
  recursion yes;
  allow-recursion { localhost; };
  forward only;
  forwarders { 8.8.8.8; 8.8.4.4; };
};

Have a look at this page. You can use the forward and forwarders statements inside your zone block.

forward ( only | first )
forwarders { ipv4_addr }

Recursive forward a zone in BIND

First of all, I would suggest you use something other than 5353 as an alternate port for DNS servers. 5353 conflicts with zeroconf/mDNS.

The reason it only works when you use vps.example.org as a recursive resolver is because that's the only recursive server that's been told that it needs to go to a special DNS server on port 5353 to find foo.example.org.

Because you can't specify a port number in an NS record, it's generally impossible to have a an authoritative server on a port other than 53. All of the recursive nameservers in the world are going to find the NS record for the domain in question and are going to try to contact that server on port 53. If you wanted them to use a different port, you'd have to configure every one of them with a forward zone pointing to port 5353.

By the way, it isn't clear why you want to host foo.example.org on a separate nameserver on a different port (or IP address). Why don't you just add the foo.example.org zone to the same authoritative nameserver that serves example.org?
