George,
Yes, once initialized it does not matter on which other port the
connection is handed off.
I don't know of any MOS notes, but google for sqlnet ALG (application
layer gateway) for further explanations by different firewall versions.
But there is a good chance that your firewall guys are actually already
knowing this and there is just some lost in translation issues about
requirements.
Kind regards,

Hi Freek
I'm then going to assume that when the connection is "handed off" to
another port for the actual connection the firewall understands that
the user will be knocking on this other port, on which the user
process is now listening.
Do you know of a MOS note other than the 2 I listed that explains
this.

George,
Normally the firewall "understands" sql*net traffic and it is
possible to mark the original port (the one on which the
listener is listening, eg 1521) as sql*net.
This way, the firewall guys only need to open port 1521 and
mark it as sql*net and no other ports need to be opened nor do
you need to switch to CMAN or MTS.
Kind regards,

You have the obligation to inform one honestly of the risk, and as a
person
you are committed to educate yourself to the total risk in any
activity!
Once informed & totally aware of the risk,
every fool has the right to kill or injure themselves as they see fit!
