DNS Fowarder

I have setup DNS forwarders on my DNS server using my ISP’s DNS server as the forwarder.  For some reason, on my firewall I see a lot of DNS traffic originating at my DNS server going to many domains on the Internet including the root servers.  Anyone know why this would be happening if I have setup my DNS server to forward out as opposed to doing the lookups itself?

They are probably DNS lookups to the root DNS servers.

And forwarding means, if my DNS server cannot resolve it first. These are probabaly just the local DNS server attempting to resolve the name.

If you use conditional forwarders, then the local DNS server sees the DNS name and forwards to a particular DNS server for that domain.

Good Luck,
