Here is what I did to setup the VPN: Help with ZeroTier routing between GL.iNet devices - #6 by goldsteinadj
As mentioned, there are other ways to detect your location. Wifi mapping, web rtc, GPS signals etc. For MOST (not all employers), masking your IP address properly will be sufficient for your laptop, since laptops for the most part don’t have GPS. Your cell phone is a different story, and would likely require GPS spoofing (or keeping corp stuff off your cell phone all together). If you work for the government/military, they MAY go the extra mile with some of these techniques. But as someone who works in IT security, MOST corporate security tools are just using your public IP address and/or GPS signals only. So for your laptop, hiding behind a properly configured router should be sufficient. For your cell phone, keep corp stuff off your phone if possible. If not possible, get a 2nd phone, enable GPS spoofing (look up on the internet on how to do this) + Zerotier app (which has the ability to funnel all traffic). Additionally, you can “block non-vpn traffic” and enforce the VPN connection in Android so your internet connection drops instead of IP leaking (in case your phone reboots, or the app crashes). I am on call, but generally, I keep corp stuff off my phone, and when on call, I just use the call forwarding option only.
