Hi guys,
I experienced an issue when I configured zone tansfer between 2 dns servers at internal and external zones. The PIX version is 6.1(5). I believe all the ports (TCP and UDP)are opened. Actually, from internal DNS server, I could query the external DNS server (which is UDP traffic), as well, I could use the 'dig' command to manually transfer the zone file from the external DNS server (which is TCP traffic). However, I could not use 'rdnc reload' to transfer the zone file from the external server (which is UDP traffic). From the firewall log, I got the following information as attached.
However, I tested from a PIX with version 6.3. The 'rndc reload' command worked.
Does anybody have some idea? Thanks in advance.

hi,
the logs which you have attached suggest the connection is bilt up properly.as well as the teardown is normal,i.e,without any interruption at either ends.It's a normal tcp close down sequence with out any flags,but the data transferred in verl low ( 1 byte ).I would recommend you to upgrade to 6.3.5 gd release as that's far more caveat free then 6.1.as far as your question as to what might cause this,i m not sure as logs look fine. ( in fact in 6.1,logs did n't use to give much info )...hope this helps.
