Plume has VPN passthrough support, allowing any devices running a VPN client to connect through a VPN service.
If you want all of your network devices to go through a VPN service, you can connect your Plume pods in bridge mode to a separate router with built-in VPN Client support.
Accessing your network from outside of your home can be done using a router with VPN Server support. In this setup your Plume pods should be set to bridge mode.
