      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
        64 bytes from 192.168.10.1: icmp_seq=0 ttl=64 time=15.586 ms

        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.

                    Never ask to ask - just ask. If you think it would get buried in a thread, just start a new thread. It's a community, everyone can help. :-)

                      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
                      dev tun
                      ifconfig 10.0.7.1 10.0.7.2
                      route 192.168.99.0 255.255.255.0
                      ROUTE 192.168.10.0 255.255.255.0 ???????????????
                      secret /tmp/static.key
                      ping 10

                      AND PFSENCE B:

                      daemon
                      keepalive 10 60
                      ping-timer-rem
                      persist-tun
                      persist-key
                      dev tun
                      proto udp
                      cipher BF-CBC
                      up /etc/rc.filter_configure
                      down /etc/rc.filter_configure
                      ifconfig 10.0.8.1 10.0.8.2
                      lport
                      push "dhcp-option DISABLE-NBT"
                      route 192.168.99.0 255.255.255.0
                      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,

                              regarding the static routing ….

                              I can ping from XP client behind PFSENCE B DD_WRT and vice versa, but cannot ping any client behind ddwrt like XP .... (after turning off local firewall)

                              XP1 ----DDWRT------PFSENCEA-------PFSENCEB------XP2 so XP1 cannot ping XP2 and vice versa.

                              Could be missing gateway on DD-wrt? there is setup IP 192.168.1.1 mask: /24 but no default gateway .....
