      question your openvpn problematic

      is it on the clients side ? if so just add
      nobind in the *.ovpn

      nobind

      that it

      here’s the symptoms client connect but traffic is not goiing thru .

        It is also site-to-site pfsense-to-pfsense, not sure if that will do anything for that.

        And other clients eg windows or linux, work just fine, but again that is an other tunnel in this case, but thanks for the tip 😊

          hahahaha
          i did some more digging !
          this is hilarious !
          now my wireguard SITEA GATEWAY is the ip of SITEB
          and my SITEB GATEWAY is the ip of SITEA !
          when the handshake occur all gateway are online !! and ping goes on !

          absolutely ASOME OR RIDICULOUS
          I PUT THE CONFIG BASE ON YOUR IP

          Interface - Site 1
          Description: WG
          IPv4: Static IPv4
          MTU: 1420
          IPv4 Address: 192.168.77.1/24

          Gateway- Site 1
          Interface: WG
          Name: WG_Gateway
          IPv4 Address: 192.168.77.2/24

          Interface - Site 2
          Description: WG
          IPv4: Static IPv4
          MTU: 1420
          IPv4 Address: 192.168.77.2/24

          Gateway- Site 2
          Interface: WG
          Name: WG_Gateway
          IPv4 Address: 192.168.77.1/24

                Super nice, seems like we were able to help eachother out a bit then 😊

                I redid some of the steps, I now have one tunnel all working now!

                  Hello,

                  I also have the same problem, site to site impossible with Wireguard on pfsense in version 2.5.2.
                  You mentioned OpenVPN, Wireguard and IPSEC in the conversation, is your last messages for solving the problem about Wireguard?

                      I have succeeded, in addition to adding the gateways on the interfaces, we must add the static routes.
                      If you follow the netgate documentation everything should be automatic :D !

                        already mentionned in that post

                        static routing is up there

                        just read carefully

                        every thing is there

                            @yazur I will try to do my best to sum it up :)

                            • Create a tunnel, on Site 1 and Site 2, eg change the port number if you do not like the default value, generate the keys for the site, it follows the setup as below.
                            • Assign the interface (eg tun_wg0) and set a static IP, this is the tunnel network, set the MTU to 1420, see settings below, i use the subnet 192.168.77.0/24 in this exampel.
                            • Set a firewall rule (UDP) to allow traffic on the WAN interface to the Wireguard tunnel port. (eg UDP port 51820 to WAN address on the WAN interface) (And no it is not a NAT rule (Port forward))
                            • Set the needed firewall rules for WireGuard and the WireGuard interface WG
                            • Add the peers, on both sites, where the public key for the peer is the opposite sites public tunnel key. At least one of the peers shall have an endpoint, the opposite can be dynamic. So the site that have and public IP, can have its peers to be dynamic, we can call that site the server (the site with an public IP) and the other sites for clientes (those eg behind a CGNAT) if you like. Also add Allowed IPs here, you will need to add the LAN IP and the tunnel IP subnets
                            • Add the gateway, with the opposite sites tunnel IP.
                            • The gateway should come online at this point and the handshake should now be green-
                            • Now set the need static route on both sites

                            Tunnel - Site 1
                            Tunnel: tun_wg0 (Site 1)

                                every thing was already said in all the post for a pfsense user to do their jobs !

                                reposting all the procedure was kind of useless but friendly :)

                                have a nice one bro

                                    That’s for the tutorial. I was following a German dude tutorial on YouTube and setting gateways for site 1 the site 1 ip and for site 2 the site 2 up. Result was losing handshake and pings after a few hours or randomly. Even with keep alive settings.

                                    For now I reverted back to IPSec for site to site vpn as is more stable and easy to setup. Manual creation of static routes and gateways it’s as bit of pain if you’re on relatively big environment.

                                    I know, I know… it’s experimental. Works great for mobile warriors though.

                                      This was working fine on version 0.1.3. Updated to 0.1.5 and now I cannot access any of my peers subnet defined in static routing. I can ping from pfsense but pinging from any address on the lan subnet doesn’t work. Site one can’t ping site 2 and vice versa.

                                        With hybrid nat the automatic nat rules for the WG interface look like a hot mess, especially if you have multiple interfaces. Anyone have examples of what it should look like?

                                          What is your goal with the Outbound NAT change? It is not required for site-to-site.

                                          If the goal is to change all traffic to the interface ip you can do that by setting to roules:

                                          Destination: * or what you need
                                          Destination port: *
                                          NAT Address WG address
                                          NAT port: *
                                          Static port: false

                                          Not sure if this is what you are looking for?

                                            After much hair pulling I finally made this work and stable.

                                            You need to specify / create and assign he gateway to the WG Interface when you create it else you'll have or sort of routing issues
                                            You also need to create static routes to the gateway with the subnets you want to access on the other side of the tunnel.

                                            Oh and the instructions above are wrong the Gateway ip needs to be the ip of tunnel on your side and not on the opposite side or it won't work.

                                            Unfortunately then entire wireguard project seems to be quite secondary at this point for negate (they didn't even bothered updating the documents)... I know it's still experimental, but ok...
                                            The developer is also never available never replies to anything in any of the platforms he mentions on his videos. He just ignores 99% of problems people are having (I hope they are not expecting us to start opening pointless stuff on redmi)
