    Greetings,

    I recently noticed having some trouble with bind on sarge (version 8.4.4-1).
    The system is an intranet server, configured to resolve all local names and
    ip-adresses (.local / 192.168.x.y) and to forward all foreign resolv-request
    to the ISPs DNS.
    forwarders {IP_1; IP_2}; //named.conf
    I use a woody based router / firewall to connect my intranet the world wide
    web.
    The firewall is connected using a ADSL-dialup-line, disconnected by the ISP
    after 24h hours. The router redials at once, if the line is
    interrupted /disconnected. (The external IP usually changes on every
    reconnected).
    I noticed, that after reconnecting, bind is not able to resolv non-local
    names. Local names can be resolved without any problem
    If I restart bind after reconnecting, bind forward foreign requests again.
    Futhermore this issue is not deterministic. Bind is not unable to resolve
    names after every single reconnect, but I was able to reproduce the issue by
    redialing manually - maybe (perhaps) it works if I get the same IP address
    again. These chance is extremly small, and cannot be reproduced easily and
    perhaps other side-effects might be a reason, too.)

    For instance:
    ping x.local
    -> works finde
    ping y.com
    -> no happens
    /etc/init.d/bind restart
    ping y.com
    -> works fine.

    What's wrong here?

    Keep smiling, thanks in advance
    yanosz
