      You can't push routes with shared key.

      You need no custom options, you only need to fill in the remote network field properly.

        OK,

        then erasing everything from custom options on client side and server side …..

        going back to the client and in field INTERFACE IP replacing 192.168.99.0/24 to 10.0.8.0/24

        after that server and client logs shows

        server:

          i have double checked on the server side:

          remote network: 192.168.99.0/24

          and client side: 192.168.10.0/24

          in field REMOTE NETWORK where:

          client network:192.168.99.0/24
          server network: 192.168.10.0/24

          So all should be perfect but still can't ping each other …....

            Where are you trying to ping from?

            A client machine, or the firewall GUI?

              both,

              in GUI on the server I try to ping client GW 192.168.99.1 and vice versa –-- no luck

              also on the XP laptop behind server try to ping 192.168.99.1 ----- no luck

              With Interface IP set to the wrong one "192.168.99.0/24" instead of "10.0.8.0/24" I can ping the other side from whatever place (GUI or XP client) in both ways....

                In firewall rules under LAN I have respectivelly rules that

                on the server all traffic should be passed from source 192.168.99.0/24

                and client from source 192.168.10.0/24 so firewall should not be the issue. Also the WAN port 64000 TCP/UDP is open on both client and server.

                  show the routing table from both sides:

                  netstat -rn

                      Do you have static routes set on the client pfSense under System > Static Routes? If so, remove it.

                      Your client pfSense box has a route for 192.168.10.0/24 on em0, not tun0 like it should be.

                        ok I see…. so after changing Interface IP on the client from right one (10.0.8.0/24) to the wrong one (192.168.99.0/24)
                        I can ping each other and on pfsence client:

                        ping 192.168.10.1

                        PING 192.168.10.1 (192.168.10.1): 56 data bytes

                        well so what can be done in order to make it right tun0? recreate vpn tunnel on the client side from scracth?

                          After you remove the static route from the system, you should just need to restart the OpenVPN process (edit/save the openvpn instance, don't need to change anything)

                          And then it should put the right routes in.

                          OpenVPN handles the routs itself, you don't need to add any static routes to the system.

                            wholly smoke !!!! it works !!!

                            In the future if I add any static route under SYSTEM>STATIC ROUTES on the client or server side is that going to affect tun0 again?

                            Thank You for your help.

                              Only if the routes you add overlap the networks you want to use the VPN.

                                      Simply just do not want to be like rest of ….. begging ..... asking .... pushy .... etc....

                                      1. I have added to my scenario DD-WRT with OPenVpn and simply connected using SHARED KEY (easiest one) so now it looks like:

                                      DDWRT ------ OpenVPN 10.0.7.0/30-----PFSENCE A 1.2.3-------OpenVpn 10.0.8.0/30-------PFSENCE B 1.2.3
                                      192.168.1.1                                      192.168.99.1                                                  192.168.10.1

                                      So clients behind DDWRT and PFSENCE A can ping each other and clients between PFSENCE A and PFSENCE B. What static route should I add (if any) and does it have to be under SYSTEM (STATIC ROUTES) in PFSENCE and respectively in DDWRT to be able ping clients behind DD_WRT and PFSENCE B?

                                      Or just extra line with route "X.X.X.X MASK" to each Open VPN client like in DDWRT:

                                      remote X.X.X.X
                                      port
                                      proto udp

                                      ping 10

                                      AND PFSENCE B:

                                      daemon

                                      down /etc/rc.filter_configure

                                      ROUTE 192.168.1.0 255.255.255.0  ???????????????????????
                                      secret /var/etc/openvpn_server0.secret
                                      comp-lzo
                                      persist-remote-ip
                                      float
                                      comp-lzo
                                      cipher AES-128-CBC
                                      verb 3
                                      mute 10

                                      2. I see that PFSENCE 1.2.3 does not have TLS_AUTH option in GUI so If I just add in server/client file config --- will it work? Or have to fallow this link http://forum.pfsense.org/index.php/topic,2747.msg16214.html#msg16214 (does it applied to 1.2.3 ?)

                                      I have added 2nd question and this is not a good sign ...... :)

                                        On pfSense B, add "route 192.168.1.1 255.255.255.0;" to the custom options.
                                        On DD-WRT, it needs "route 192.168.10.1 255.255.255.0;" - That should be all you need.

                                        As for TLS on 1.2.3, I'm not sure what all you need. I've never tried it (I only use 2.0 these days) - but if someone has a howto, it may work.

                                            have answer to my question regarding TLS-AUTH

                                            simply go to PACKAGE MANAGER and install OpenVPN-Enhancements (TLS-auth and client/server-options)

                                            unfortunately, it cannot be uninstall-ed later  so do not know if affects anything …..

                                            Cheers,
