Hi GlennD, thanks again for your support.
I solved the problem with the firewall, my IT department unblocked the IP of my machine and I obtained the connection.
I made the two PCs participate in the same previously created Mesh network, entering "Network ID" and "Password"
My PC pings the remote PC...
The remote PC doesn't ping mine even though they both have the green dot... and I'd like to understand why.
The next step will be to understand if having reached the Customer I can also download the device connected to it.
I hope to receive your help again.
Thank you.
