Forwarding/Caching
My DNS server (gto.dynu.com) is currently forwarding/caching DNS request to my ISP's DNS servers if i were to set a domains nameservers as gto.dynu.com and have my server forward request to let say ns1.dollardns.org and ns2.dollardns.org would it work?

I've never setup forward zones before. I created the below in my config and it works very well. I created a delegation.test zone with everydns.net and my server is able to resolve that domain cause of the below:

#
# A forward zone example
#
zone "delegation.test" IN {
&nbsp;&nbsp;&nbsp;&nbsp;type forward;
&nbsp;&nbsp;&nbsp;&nbsp;forward only;
&nbsp;&nbsp;&nbsp;&nbsp;forwarders { 64.158.219.3; 216.218.240.206; 80.84.249.169; 63.219.183.200; };
};

The question is why though?

Actually, I may be wrong. I've done a bit more playing around and it might not work. You see, forward zones are meant for recursion. A client must request the zone information from you with the "recursion desired" flag turned on. This doesn't happen if the client expects you to be authoritative for the zone. So your server may not return the information needed.

I strongly recommend that you do not use forward zones on authoritative servers.
