DMZ and php page issue

Question

Hi,
We have an Oracle database server 11.2.0.1 that run in Oracle Linux version 3.8.13-16.2.3.el6uek.x86_64, and a Linux 32-bit client server that run in Linux CentOS 6.2.
From the 32-bit client server in the DMZ if we run the query below by sqlplus we have no problem. When we run the same query from the same client server but by php page, it does not return more than 65 row. But (WHERE ROWNUM <= 64) it returns the result fine. If we move the 32-bit client server into LAN, we do not have the issue at all. If you have experience with DMZ or firewall for the situation, please help.
Php query:
'SELECT * FROM (SELECT
        p.T$NAMA AS NAMA,

Answer 1

Maybe you run the statement with 2 different users and there could be some policies enabled for those tables ( VPD )
