Hello,
I have not found a solution for my problem in this newsgroup so I will post
it here.
My configuration: SuSE7 Linux, Bind8, Dial on Demand, masquerading, dynamic
IPs.
My first attempt was to set my providers name server address as forwarder
plus forwarding only.
Problem: If a name server request (unfortunately UDP) has to be forwarded to
the name server of the provider, DoD opens a connection, but the request is
lost, because UDP packets with a dummy IP (if the connection is not
established) can not be patched to "real IP" (after connection) .
My solution: I added my providers name server IP several times to the
forwarders list. This worked fine, because the name server now requests more
often the external name server.
New problem: Now I discovered that, even if my local dns has cached the
requested data, the forwarders will be asked for a specific name.
New solution: no forwarders, not forward only -> only root name servers ->
this works fine but this is a DIRTY solution.
Can anybody tell me, what I do wrong?
Georg
