I don't have another wire-guard device unfortunately and i think relayd is my only option. I'm in a share house and my room is far from the Main router. Main cannot mesh and i cant connect via cable.
I have tried the solution in here and it works. WireGuard "server" on Relayd client bridge device [SOLVED]
Now i can connect to wire-guard VPN and also have internet access.
I cant access devices connect to the OpenWrt AP or lan ports. I can only connect to computers connected to the wlan from the Main ISP router.
I have my Raspberry pi on 192.168.1.150 and when i connect my laptop to the wg VPN and ping it i get this..

192.168.1.100 is the ip address of the OpenWrt router.
