      Sure.

      Forget about site2site.

      I have server that is configured as remote access server (roadwarrior).

      Everything was working just fine until today.

      Now it can`t check cert:

        Would you recheck with the depth set to "one" and see if that error goes away please?

                No. Steve just figured there must be something to it. This all works fine with TLS and user auth on latest version, and nothing there has changed in some time. I upgraded a variety of test and production setups to latest and they all still work fine, and did a couple new configs from scratch which also worked fine.

                Could you get me into your system to review? Can PM me to arrange specifics if so.

                  There was snapshot issue or bad upgrade.
                  Now I`m on 2.3.b.20160115.1858 and roadwarrior works.

                  Now I have to test SSL/TLS peer to peer to confirm that working too.

                      hmmmm could it be topology issue on 2.2.6?
                      mismatch between 2.3 server (subnet) and 2.2.6 client (net30) ?

                        UPDATE:
                        If I leave all settings like they were and change only from SSL/TLS TO shared key VPN works.
                        With TLS I get that add route error.

                        wth??? :)

                          There is no way at all for me to connect 2.3 box to 2.2.6 with Openvpn SSL/TLS.
                          With shared key it works just fine.

                            Look at screenshot.
                            Shared key and ssl/tls don`t have same settings under tunnel options.

                              Shared key works for me, SSL/TLS not.

                                In addition, when changing modes (shared key to ssl/tls) firefox needs like 15 seconds to display other options while IE changes options instantly.

                                EDIT:
                                This only happens on firefox NIGHTLY build, so nevermind that.

                                    They're not supposed to have all the same settings. Which specific setting are you referring to?

                                        Tunnell settings MUST be same only encryption should vary. 2.2.6 has same tunnell settings for both methods and encryption different which is ok.
                                        Clearly there is something wrong with openvpn gui and how it generates config.
                                        Between 2.2.6 no problem at all.

                                          There is a difference between the Tunnel settings display (Peer to peer (Shared Key) ) 2.2.x vs 2.3

                                          I will correct that. I'm sure it will make a difference to the shared configuration though. I will make a note here once a correction has been pushed and perhaps you would let me know if you see any improvement.

                                          Thanks for continuing to work on this!
