Hi, I’m working on a small project at university. What I’m trying to do is: sending and receiving data between 2 OPC UA Client application.
Because of the small size of my project, I intend to use Prosys Simulation Server to execute it (Client 1 ……. Prosys Server ……… Client 2).
In the next step, I create a virtual machine (Azure), and its public IP addres is (for example) and private IP address is , then run the Prosys Server on that virtual machine.
Here’s the problem:
– I try to ping from my physical device and it works.
– I try to connect a remote Client (on my laptop) to the Prosys Server (on virtual machine) with url: opc.tcp:// -> It doesn’t work
– I try to connect a local Client (on virtual machine) to the Prosys Server with url: opc.tcp:// -> doesn’t work, and url: opc.tcp:// -> works
– In the Prosys Server, I go to tab Endpoint -> Bind Address -> Custom -> Configure… and there are only 2 addresses: and Does it need to have an address like there to connect from my remote Client?
So can you suggest me some solution to my problem? Thank you so much

What type of connection do you have between your laptop and the VM? If you’re using NAT, you will need to forward ports of the VM to expose them publicly.
