Hi community

I'm new to this forum.
Let me describe my problem....I've got 2 laptops one at my home and one at my parents. I've connected them through a vpn. The vpn server is at my home. Both laptops connect to the internet through wifi.
The laptop at my parents is the client. I've got a device which is connected on the lan port (eth0) and it gets an ip address. How can I forward the eth0 port / device / ip address so that I can see it on my server?
I do got some networking knowledge but I need some help on this one.

I've tried to bridge the connection on the client (eth0 port and wifi) but I don't see anything on my client. Maybe I need to do more configuration?
