Hello, it seems you can't enable the Android Settings for "Always-on VPN" and "Block connections without VPN" and enable a split tunnel / allow local LAN access at the same time. All traffic is always forwarded to the VPN without exception.
I have tested this using Proton VPN but found reports this seems to be same with other VPN configurations as well.
It's important to me to never reveal my public IP but I also need to backup my photos and get a copy of my password manager database from my LAN because I don't store this content in the cloud.
Does anyone know of a solution?
I would even resort to a serial (USB/Bluetooth) sync but don't see any obvious apps that would automate this.
