The ports used by the GUI applications for various services are not static but are assigned dynamically (the next free port on the system), normally this cannot be avoided on PC systems over which we have no control (or in most cases you don't normally want to), in this case you might have to allow a range of ports in the GUI direction.

(*)  this only applies to APPoloGUI: If your network is very restrictive (for dynamic ports too) you can force the LynxCentraal /greenGUI  APPolo Control GUI to local port 2301.

To do so, right - click on the LynxCentraal /greenGUI / APPolo Control GUI desktop icon, click on properties and enter the following behind the path target entry:

 -localPort 2301 


Target: "Path/to/the/APPolo.exe" -localPort 2301

Apply the settings and start the LynxCentraal / greenGUI / APPolo GUI by using this desktop icon.
