Ich habe einen Linux (SuSE8.2)-Rechner als Server/Router im Netzwerk

Er übernimmt die Einwahl ins Internet - über ständig wechselnde Provider über ISDN. Wegen der starken Tarifunterschiede geht es nicht anders. Damit die Clients von diesen ständigen Wechseln "nichts mitbekommen", läuft auf dem Server ein bind. Dieser soll alle Anfragen an die jeweils vom Provider via DHCP übertragenen Nameserver weiterleiten. Er ist sozusagen der "Master-DNS" im LAN. Tut er auch, aber nur bei 99% der Anfragen.... Der Rest landet im Nirwana - keine Idee, warum.

Hier meine named.conf:

+++++++++++++++++++++++++++++++++++++++++++

options {

# The directory statement defines the name server's
# working directory

directory "/var/named";

# The forwarders record contains a list of servers to
# which queries should be forwarded. Enable this line and
# modify the IP-address to your provider's name server.
# Up to three servers may be listed.

#forwarders { 10.11.12.13; 10.11.12.14; };

# Enable the next entry to prefer usage of the name
# server declared in the forwarders section.

#forward first;

# The listen-on record contains a list of local network
# interfaces to listen on. Optionally the port can be
# specified. Default is to listen on all interfaces found
# on your system. The default port is 53.

#listen-on port 53 { 127.0.0.1; };

# The next statement may be needed if a firewall stands
# between the local server and the internet.

#query-source address * port 53;

# The allow-query record contains a list of networks or
# IP-addresses to accept and deny queries from. The
# default is to allow queries from all hosts.

#allow-query { 127.0.0.1; };

# The cleaning-interval statement defines the time interval
# in minutes for periodic cleaning. Default is 60 minutes.
# By default, all actions are logged to /var/log/messages.

cleaning-interval 120;

# Name server statistics will be logged to /var/log/messages
# every <statistics-interval> minutes. Default is 60 minutes.
# A value of 0 disables this feature.

statistics-interval 0;

# If notify is set to yes (default), notify messages are
# sent to other name servers when the the zone data is
# changed. Instead of setting a global 'notify' statement
# in the 'options' section, a separate 'notify' can be
# added to each zone definition.

notify no;
};

# The following three zone definitions don't need any modification.
# The first one defines localhost while the second defines the
# reverse lookup for localhost. The last zone "." is the
# definition of the root name servers.

zone "localhost" in {
type master;
file "localhost.zone";
};

zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0.zone";
};

zone "." in {
type hint;
file "root.hint";
};

Hat jemand eine Idee, warum das bei einigen wenigen Seiten keine Namensauflösung gibt?
