Incoming connections

I failed to open port in router because complexities with my VPN. Not even sure this VPN support forwarding. But after activating incoming in node settings i seem to get a few incoming anyway. (Between 3-6) First i thought this was because UPnP or so but that is not active in the router.

How can this be? And if its available for incoming somehow, why so few?

Update. I managed to open the port and get incoming when not using the VPN. Set a static IP for the PC running Umbrel and opened in router. However, i would really like to be able to have the VPN on so no idea how to set that up. Any assistance appreciated :pray::pray::pray:
