Synology NAS Surveillance Station & Mobile app DS Cam

I am connecting to my surveillance station NAS using DS Cam, but I cannot get a direct connection so the system uses the relay which is less responsive. I would like to figure out how to get this working right.

I enabled these ports in the firewall, too: TCP 5000,5001 and UDP 19997,19998. After some troubles it now seems to work, but is this the right config and as minimal as it can get?

Changing/activating the Surveillance Station ports does unfortunately not change the port used by the DS cam app. It seems all DS mobile apps insist using the Port of the diskstation manager.
