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
having the same result.
Here's a packet capture that better describes what is happening.
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 188.8.131.52, A 184.108.40.206, A 220.127.116.11, A 18.104.22.168, A 22.214.171.124, A 126.96.36.199, A 188.8.131.52, A 184.108.40.206, A 220.127.116.11, A 18.104.22.168, A 22.214.171.124 (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.
