Forward Wireguard traffic to ETH1

Forward Wireguard traffic to ETH1

I setup a wireguard server with AWS, setup the wireguard client with a raspberry PI. Now I need to redirect the WG traffic (wg0) to eth1 -- my goal is to get a IP from my WG server when a client is connected to the PI eth1 (Full tunnel) my WG config

[Interface]
Address = 10.1.1.1/24
ListenPort = 51820
PrivateKey = ##
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

[Peer]
PublicKey = ##
AllowedIPs = 10.1.1.2/32

I installed Netplan but I'm very lost with the config (I need to sent WG0 traffic to ETH1) does the follow config make sense : (probably not...)

network:
    version: 2
    renderer: networkd
    bonds:
        bond0:
            dhcp4: yes
            interfaces:
                - wg0
                - eth1
            parameters:
                primary: wg0

It's would be even better for the Raspberry PI to joint my UniFi VLAN (uplink) and get an IP from there but still sent/receive all the traffic from WG server but that's to complex for me I guess UPDATE: should I add the WG config to Netplan?

tunnels:
  wg0:
    mode: wireguard
    addresses: 10.1.1.1/24
    peers:
      - keys:
         Public_key?
        ...
    key: Private_key?
network:
    version: 2

            interfaces:
                - wg0
                - eth1
            parameters:
                primary: wg0
