Which ports have to be open to access the robot controller through VPN?


I'm trying to reach a robot over VPN.

By opening port 5512, 5513, 5514 and 5515 it's possible to connect to the robot, but I'm unable to browse the RAPID or even take backups..

The ports 20 and 21 is also open.

I got this error in RobotStudio today:
The remote server returned an error: 227 Entering Passive Mode (10,47,46,213,4,28)

Best Regards,
