Please do correct me if I am wrong.
You are saying that it is not possible to have only server port opened, I
need to open port 443 in both sites.
Site A port 443 need to be open from PC and from the firewall.
Site B port 443 need to be open from PC and from firewall.
No, I didn't meant to say that.
I said: You can have a listing port 443 in Site A and/or in Side B as you
As soon as you have a listening port on any side, then to be able to reach
that port from the outside, you have to "open" the port in the
firewall/router/whatever on the box which is on the physical link and also
on the computer itself. This is not related to ICS but simply how TCP/IP
If this is correct than,

A client PC can never been reached. This is exactly what make the difference

input/output goes from/to the connection between client and server.
I cannot use WMI to collect the client system info or modify the client
I am just hoping that I am totally wrong!!
I think you have not figured the software layers in your head.
One thing is the link layer (the connection between client and server).
Another think is the application layer (commands/responses transported by
the link, in both direction)
