Oracle behind a firewall

150473Mar 13 2002 — edited Nov 24 2003

I have Oracle 8i installed on a W2K. There is an
Application server in the DMZ which is required to connect to
the Oracle box via a firewall system.

I need to add a rule in the firewall to let it go (that is no problem).
The default listening port for Net 8 is 1521 (listener), eventhogh when the Oracle do not answer using 1521, I found that the port number used by Net8 after authenticated is varied.
I need to set a range of ports to the Oracle answer, it cannot be any port.

I guess the solution (using the firewall, not a VPN) is to set a range o high ports into the firewall and try to limit the response from Oracle to this range.

How can we set a range o high ports response into Oracle? I am using 8i.

Best Regards,

Rodolfo
