Problem Statement
Where can I see the ports used by the OPC UA Configuration tool for v10 

Solution

InfoPlus.21 Server automatically configure the firewall ports during installation. If you want to see which ports are being used by the applications for the OPC UA connection, please follow these steps.

1. Open UA Configuration tool.
2. Click on "Manage Application" Tab
3. You need to have IP21OpcUAServerHost.exe select on Application to Manage (see image below)

if IP21OpcUAServerHost is not on the options, click the "Find" button --> ProgramFiles --> Aspentech --> InfoPlus.21 --> db21 --> code and select IP21OpcUAServerHost.exe and open it.

4. Click on "Manage Firewall Access"  and a window will open named "Open Firewall Ports"(see image below)


If you check the box of  "4840" or "52601" you will be able to see the ports used by application


 
Check the box of "Application Access Granted" and you will be able to add or remove any port.
