I have been back and forth with some users here about creating a VPN using my Raspberry Pi 3 as a hotspot (OpenVPN client) but being able to bridge it to my other Rasperry Pi 3 at home (OpenVPN server).
A great user was able to help me out with getting it to work 100% as a layer 3, however I am using a device that in order to interact with the other network devices on my server's network, it requires a bridged network using a layer 2 VPN.
I have tried many many things, spent countless hours of free time off-work and weekends. Googled probably hundred's of times... I can't seem to ping or see this device on my server's network at all.
If I ssh to the client or any other Raspberry Pi's in the client's network, I am able to ping this device. But outside of the client's network I just can't ping at all.
All the information to what my setup is is located in here: Pi 3B+ As Hotspot + OpenVPN
But basically I need to convert a working Layer-3 OpenVPN network to a Layer-2 OpenVPN network.
I am fairly sure this device requires a bridged network... it needs to have the same subnet and IP range as the server and hence the need for a layer-2 network.
I know there is some information out there, but I should specify, I'm hoping to get this done using raspbian-lite. I don't want any kind of UI or graphical interface since this would draw more resources than the lite version. I did find this video which seems quite useful. But I can't seem to be able to figure it out.
Your help would be greatly appreciated figuring this out,
Thank you in advance.
