I'm using a raspberry pi with raspbian. It's permanently connected to a wireguard VPN (the VPN doesn't support port forwarding from the external VPN address). I also want to host something on the raspberry pi and make it accessible over my home internet.
When the VPN is not connected:
The service works from inside my network.
The service works from outside my network. So the issue is not port forwarding from my modem to the pi
When the VPN is connected:
The service works from inside my network.
The service does not work from outside my network.
