      Hi

      I have two network

      This is the diagram :

      0_1546259043944_Capture44$.PNG

      I would communicate from the workstation 1 to the workstation 2

      I use Openvpn site to site

      Server (Pfsense 1) :

      Server mode : Peer to Peer (Shared Key)

      Interface : WAN

      Port : 1193 (i use 1194 for openvpn remote connection)

      IPv4 Tunnel Network : 172.16.20.0/24

      IPv4 Remote network(s) : 192.168.6.0/24

      -> Save
      I add a firewall rules to allow udp from any source to wan address (destination) via port 1193

      Client (pfsense 2)

      Server mode : peer to peer (shared key )

      Server host or address : X.Y.Z.69

      Server port : 1193

      Shared key : the same in pfsense 1 of corse

      IPv4 Tunnel Network : 172.16.20.0/24

      IPv4 Remote network(s) : 192.168.1.0/24

      -> Save

      the state is always " reconnecting; ping-restart " (i restart the service in both pfsense , the 1193 is open in the two router )

      openvpn	70003	Re-using pre-shared static key
openvpn	70003	Preserving previous TUN/TAP instance: ovpnc1
    openvpn	70003	TCP/UDP: Preserving recently used remote address [AF_INET]X.Y.Z.69:1193

      openvpn 70003 Inactivity timeout (--ping-restart), restarting
      openvpn 70003 SIGUSR1[soft,ping-restart] received, process restarting

      How i can resolve that ??

        The upstream routers will have to be configured to forward port UDP/1193 on the server side to pfSense.

        A comprehensive network diagram is worth 10,000 words and 15 conference calls.
        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                From Pfsense Openvpn Documentation

                IPv4 Tunnel Network : The suggested default in the GUI of 10.0.8.0/24 is sufficient, but any random unused network inside of the RFC1918 space is recommended. For site-to-site shared key, only a /30 is used, not a /24, even if /24 is specified.

                  Yes, but he should get any connection first anyway.

                      It's always good to run through the Troubleshooting Network Connectivity guide first, when it is still not working he can show us the logs. Config screenshots (OpenVPN + Firewall Rules) are always welcome too. ☺

                            I know this question has been asked a plethora of times before and I have looked over probably 100 different answers and still can't seem to get this to work.

                              FYI : the IP public in the client side is not static , i look to what is my ip and i used the address

                                I don't know what the rule is, but

                                1. it does not work for you ( 0/0 )
                                2. the number 12 at the end of the address is different from the Boston address x.y.z.13
                                  If the client does not have a white ip, it is better to put any source
                                  This is just a note because the following rule allows everything on TCP/UDP protocols
                                  You show a small part of the log . We need more information. You need to see what happens at the moment of connection

                                Do I understand correctly that the connections on port 1194 work without problems ?

                                Farther
                                in server settings you specify a remote network 192.168.4.0/24 . The picture shows 192.168.6.0/24. Mistake ?

                                  yes the public ip is not static --> i put the source to any

                                  i have remote vpn connection to the server side using the port 1194 (using ssl/tls + local database) , it is work

                                  in the picture , yes , miskate , no 192.168.6.0/24 but 192.168.4.0/24

                                  the log is the same , i put the log in the server side

                                  there is the log of client side :

                                  Jan 1 14:44:55 openvpn 28395 Inactivity timeout (--ping-restart), restarting

                                  Question : the time of the two firewall is not the same , (time zone ) , any effect on openvpn 😢 😢

                                          Your configuration looks fine. I would be sure the traffic is actually passing though all the upstream infrastructure.

                                          It doesn't look like you are posting any connection attempts in the logs. Almost impossible to say what's wrong based on what we have.
