Extending LAN's across the internet with Wireguard

Hi everyone.

I bought two Mikrotik hEXs routers and am trying to set up the following.

I have Wireguard set up on a Linux server as a midpoint. The interface on the server has the IP 192.168.252.254

I want to use the Microtik routers as Wireguard clients/peers that have port 1 as DHCP internet which connects to my Wireguard server (known public IP) and the remaining ports as a LAN that is connected over the tunnel. Basically linking one LAN subnet between two sites. These can be separate subnets, as long as they can talk to each other.

I can use windows / iOS apps to connect and talk over the tunnel, but am struggling to accomplish this with the Mikrotik routers.

Can anyone help with this configuration? Basic drawing of what I am trying to do below. All IP’s on the LAN will be static.

Thanks!
