Problem with Bind


Any create trouble shooting advice will help. Here's my situation.

I have a named server for my inside domain, which is also a forwarder. It does not appear to be forwarding. I've eliminated routing issues as I can ping anything on the internet using strictly IP.

I double checked that fowarders are configured, and have tried with and without

Code:
forward only;
having the same result.

Here's a packet capture that better describes what is happening.

Code:
04:04:40.985153 IP redhatdns1.domain.local.64221 > dns-cac-lb-02.rr.com.domain: 46278+% [1au] A? google.com. (39)
04:04:41.009091 IP dns-cac-lb-02.rr.com.domain > redhatdns1.domain.local.64221: 46278 11/0/0 A 74.125.227.99, A 74.125.227.100, A 74.125.227.101, A 74.125.227.102, A 74.125.227.103, A 74.125.227.104, A 74.125.227.105, A 74.125.227.110, A 74.125.227.96, A 74.125.227.97, A 74.125.227.98 (204)
04:04:41.009825 IP redhatdns1.domain.local.domain > host12.domain.local.58606: 62553 ServFail 0/0/0 (28)
If you look closely, you'll see that the configured dns server redhatdns1 requests information about 'google.com', gets a reply (verified to be good IPs), and still forwards 'fail' to host12.

Any ideas?

Check the zone file to see why you get the error in bold above

Logs revealed insecure source so it wasn't passing the resolved addresses along. Adjusted time, fixed now. Thanks!
