    DNS test result. What's wrong?


    I am setting up a Red Hat Linux DNS server sitting on DMZ network. Mu goal is to
    have it work as a local DNS cache server to reduce outboubd network traffic. Also,
    I think our ISP's DNS servers are not very effcient.
    Below is my test results. Could somebody tell me what's wrong with my setup by
    looking at results? Thanks.

    On both DNS server and client:
    ( www is on 10.0.0.x DMZ network, pecap1 is on 192.168.0.x Intranet )

    dig www.mydomain.com -> 10.0.0.9
    dig www -> connection time out, no server could be reached
    dig -x 10.0.0.10 -> pec80.mydomain.com
    dig -x 192.168.0.11 -> pecap1.0.168.192.in-addr.arpa.
    dig pecap1 -> connection time out. No server could be reached.
    dig pecap1.mydomain.com -> Status: NXDOMAIN

    nslookup>www -> name: www.mydomain.com
    address: 10.0.0.9

    >www.mydomain.com -> name: www.mydomain.com
    address: 10.0.0.9

    >192.168.0.11 -> 11.0.168.192.in-addr.arpa
    name: pecap1.0.168.192.in-addr.arpa

    >pecap1 -> connection time out. No server could be reached

    >pecap1.mydomain.com -> server can't find pecap1.mydomain.com: NXDOMAIN
