I would like to use the site-to-site VPN with 2 Firewallas to directly connect into my home network where the home Firewalla is connected to and use the DHCP server of my home network for devices that connect to the remote Firewalla. Is this possible and how do I configure this? So far the remote devices have to use the DHCP server of the remote Firewalla. Otherwise, if I deactivate the remote Firewalla DHCP server, the remote devices do not find a DHCP server.

  Not possible

  WireGuard and OpenVPN are layer 3 VPNs, meaning they need to operate in their own network. If you want DHCP to happen over VPN, you will need L2TP. 

  Unless you have a very valid usage, l2tp are likely a bit more complex than simple layer3 vpns
