Automatic connection URL switching based on external or internal network. #1620
Description
Is your feature request related to a problem? Please describe.
Unfortunately, like many users, I have an ISP with CGNAT which prevents external access to the local network. To get around this, we can use a VPN or some tunnel. However, with this, the Nextcloud URL changes to an external version.
Describe the solution you'd like
For performance and practicality reasons, ideally it would be interesting to change the URL automatically based on whether a VPN is connected or if it is outside the configured default Wi-Fi network, just like Home Assistant and the Immich app do today.
Describe alternatives you've considered
Using the tunnel always consumes credit with each upload, even on a local network.
