Hi there,

DNS Requests from Server to Server normaly uses UDP 53 (Source and
Destination Port). However, if problems occur or packet size is > 512
bytes, it will change to Source Port >=1024 TCP and destination port 53

Subject: [suse-security] SuSE firewall2 configuration for zone transfer

Hi list,

I just setup name server for our domain. I allow-transfer on named.conf
to external server outside our domain for secondary name server.

allow-query { any; };
allow-transfer {; };

When I check on the log (/var/log/messages) there are several lines show
that the zone transfer to that server on highport is not allow like this

Jul 22 13:25:25 mail /usr/sbin/named[28877]: client
::ffff: zone transfer denied

I think it is because the firewall, so I check the firewall
configuration. But I think everything is Ok (correct me if I'm wrong). I
put the lines


Anybody can give me advice?

Kind Regards,
M. Edwin
