    Well, sorry to chime in here, but you're just suggesting a
    work around, not a real solution (which is to be running
    a caching named on the gateway machine).

    Uli, could you check if your named works as expected?
    The following applies to 5.x, adjust as necessary for 4.x:

    1. does named indeed run on the gateway?

       gw# ps ax | grep named

      277 ?? Ss 8:29.33 /usr/sbin/named -u bind -t /var/named
    18582 ?? Ss 1:54.00 /usr/sbin/syslogd -l /var/run/log -l /var/named/var/r
    81756 p1 S+ 0:00.02 grep named

    2. does named listen on all relevant interfaces (sockstat -46)?

       You should get something like this:

       gw# sockstat -46 | grep bind

       bind named 277 20 udp4 192.168.254.1:53 *:*
       bind named 277 21 tcp4 192.168.254.1:53 *:*
       bind named 277 22 udp4 127.0.0.1:53 *:*
       bind named 277 23 tcp4 127.0.0.1:53 *:*
       bind named 277 24 udp4 *:59582 *:*
       bind named 277 25 tcp4 127.0.0.1:953 *:*

      (one random port must be open to the outside world, so named
      can get replies (?), other ports must be open to the inside net(s))

    3. using dig from the gateway, querying the local named,
       whan happens?

    4. using dig from a host != gateway (on your local net),
       what happens?

    5. Can you ping outside NUMERICAL IP address from your local net?

       % ping 66.94.229.254 (www.altavista.com)

    Regards,
    cpghost.
