May 13 10:46:10 dns3 named[4352]: client 127.0.0.1#49456: query '102.10.1.10.in-addr.arpa/IN' denied

When telnet to dns1 internal IP the response is slow because the localhost of trying to resolve 10.1.10.102 (firewall NATed IP).

how to over come such a problem?

Is the response any faster if you telnet by ip address. If so, you are getting slow dns response.

The quick answer is to use faster dns servers.

/etc/resolv.conf

Make sure that all name servers can be pinged in a reasonable amount of time. Its probably better to have a locan DNS source verus one on the public Internet.

i tried another step that is to use sam.
the steps are as listed below.

Sam -> networking and communication -> DNS-BIND ->DNS Local Name Server

Change the ip to the current ip configuration.

now everything is running like new.
would try out the other method when i swap machines again.

thank you

It sound more like your router or name server is not configured correctly for NAT.

Make sure your BIND files are correctly formated for your named, you may want to review your syslog log and make sure the address you are translating is actually being picked up by named.

Make sure you had your inaddr file and the PTR record setup correctly for the natted subnet, also check the name file points to the correct natted server address via an A RECORD.
