        please try checking "dynamic"
        Doing so, you only have to set parameters on the "fixed" side...
        (client side will "use" these params in the [Peer] section)

          according to your screenshots, you should have :

          [Interface]
          PrivateKey = <Device 1 private key>
          Address = 172.16.16.1/24
          DNS = 172.16.16.254
          
          [Peer]
          PublicKey = <Server/pfSense public key or in your words FWpubk>
          AllowedIPs = 172.16.16.0/24, 10.0.0.0/24
          Endpoint = wg.domain.io:55120
          

          pinging 172.16.16.254 from client works ?

            @f-meunier That didn't help, setting it to Dynamic, I can surf and write this through this tunnel, but I cannot reach the inside.

              also confirm in pfSense' peer config that "Public Key : device 1 pkey" is the public key of the client

              (not the private key from [Interface] PrivateKey)

                sorry, I did not understand the situation.
                You have a computer connecting to the pfSense through the WG tunnel, you manage to surf through but can't access internal network 10.0.0.x /24 ?

                according to your config, it's not a "catch all" tunnel. Your computer access to the internet will not use the tunnel, but its local router/gateway directly...

                  @f-meunier Yes I am testing with my computer to see if it works.
                  First question - yes. Switching to 4G network activating the tunnel.
                  I cannot ping anything on either 172.16.16.0/24 or 10.0.0.0/24.

                    let's summarize.
                    Your computer client should have 2 interfaces :
                    LAN interface (let's say 192.168.1.1/24)
                    wireguard interface : 172.16.16.1/24

                    client config is

                    [Interface]
                    PrivateKey = <Device 1 private key>
                    Address = 172.16.16.1/24
                    DNS = 172.16.16.254
                    
                    [Peer]
                    PublicKey = <Server/pfSense public key or in your words FWpubk>
                    AllowedIPs = 172.16.16.0/24, 10.0.0.0/24
                    Endpoint = wg.domain.io:55120
                    

                    pfsense has public IP wg.domain.io
                    LAN interface IP is 10.0.0.254/24
                    wireguard tunnel (tun_wg0) is bound to interface WG_INTERFACE
                    WG_INTERFACE has static IPv4 172.16.16.254/24
                    tunnel listen port = 55120

                      On the client computer side, what is the output of "route print -4" ?

                              the routes to 172.16.16.0/24 and 10.0.0.0/24 should appear in the list

                                  well, your tunnel seems effectively up, and the routes are there.
                                  what is the pfSense config of LAN interface ? 4th byte of 10.0.0.x address ?

                                    can you give the pfSense STATUS > Wireguard

                                      One last check on WG_INTERFACE

                                      Verify that "Block private networks and loopback addresses" and "Block bogon networks" are UNCHECKED

                                          what is curious :
                                          route 10.0.0.0/24 should be accessible through a gateway -> flag " G" missing.

                                          really need to know your macOSX LAN IP...

                                          also can you explain "I can surf and write this through this tunnel, but I cannot reach the inside."

                                            set up a debian client to check

                                            Got a route to wg subnet and pfSense (172.16.16.254 in your case)
                                            Had no route to the remote LAN subnet (10.0.0.0/24 in your case)
                                            (bizarre since it's in the WG client config !)

                                            Eventually, I manually added the route to 10.0.0.0/24
                                            ip route add 10.0.0.0/24 dev wg0

                                            Now I can ping a machine in subnet 10.0.0.0/24

                                            I will check why the route is not automatically added in the routing table even though it is present in AllowedIPs list...
                                            It IS automatically added on windows client...
