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.

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!
