VPN routings

Hello I need help configuring GL-MV1000.

I have main Sabai VPN Server on in a local location Home and I have connected GLMV100 VPN WireGuard Client on in a location Remote.

I can tell that if I’m in location Remote, I can access all devices in either locations, but
If im in location on the home server, I can access only GLM1000 device itself, no devices connected to it which it is my issue. I think it has something to do with routings, but i could be wrong.

Can you please let guide me in the right direction so i could have full access to all devices in either locations Home and Remote. Thanks, Piotr
