Hi, I want to know if I can setup a WG server (eg: tunnel mobile phone connection to WG) & route server traffic out to a WG Client (eg: MullvadVPN)?
On the WG Client, can I set specific routing policies? (eg: some devices do not go through WG)?
In this case, you should connect the client to server directly. You can use one router as WG server, and another one as WG client.
We are developing routing policy for now, it will be available soon. If you want to configure it by manual, it might be a bit complicated.
