If I run the VPN on both the Beryl AX and my laptop I can reach my home LAN device but not if I only have one or the other running. Obviously running the VPN twice isn't practical and defeats the purpose of setting up the VPN just on the Beryl which was half the point of getting it.
Looks like it might be a subnet issue. The AirBnB I'm at has the same 192.168.1.x subnet as my home LAN
