OpenVPN Layer 2 Bridge

Hello all, I am looking to use OpenVPN in a layer 2 bridge to LAN. Currently when I connect to router (Slate) I get an IP that is not on the same subnet of the LAN. Is there a way to change this operation?

We have this development plan, but the priority is relatively low. Before that, you can try the configuration in the reference link OpenVPN bridging - #7 by Shadow6
