On MacOS (but to my knowledge also on other platforms) Proton VPN provides an allow LAN connections option in the settings which enables the machine to access other devices on the local network (printers, smartphone, TV, etc.) even when the VPN connection is running.
My questions are as follows:
- Does allowing LAN connections make the VPN connection less secure in any way?
- If not, is there any reason as to why Proton VPN defaults to leaving this turned off?
I am aware that there is apparently an issue with the Kill Switch and the Allow LAN Connections options being mutually exclusive, but I was wondering whether there is more to it than that.
Thank you for the detailed reply. I completely forgot about the situation like a Pi-Hole that would slip through the proverbial cracks as being a local device that also sends outbound requests on demand though.
