          The only differences I see between the two TLS files are these:

          2.2.6: <topology_subnet>2.3:    <topology>subnet</topology>

          But that is deliberate and is accommodated in the system.

          So I don't think we have a GUI issue.

          I'll check elsewhere.

          Here: https://forum.pfsense.org/index.php?topic=105341.msg588703#msg588703 you posted your OpenVPN config files. Could you do the same again but from 2.2.6 SSL/TLS (working) and from 2.3 SSL/TLS (NOT working) ?

          That way we can check the XML -> OpenVPN translation.</topology_subnet>

              I don`t get it any more.

              Why the hell shared works and SSL gives me this in logs:

              And tunnel shows as up in status -> openvpn.

              I really don`t get it anymore.

                Looks like there is a problem in that "topology subnet" is being added to the config when it should not. There is a dependency on the tunnel network size that may be broken. We are testing now.

                    About topology…
                    Mentioned it here: https://forum.pfsense.org/index.php?topic=105341.msg587367#msg587367 but nobody bite it :)

                      Fix was just pushed.

                      Please gitsync and let me know if it helped

                          Does the openvpn config file still have "topology subnet" at the end?

                              Then I suspect that either the gitsync was too early, or you need to reboot.

                              It is no longer in my config file. I created a new server and tested with that.

                                    OK. First let's make sure you really did get the updated file.

                                    please use Diagnostics->Edit file and open the file /etc/inc/openvpn.inc  Then using the new GoTo control, go to line 1066.

                                    You should see:

                                    // If the server is not a TLS server or it has a tunnel network CIDR less than a /30, skip this.

                                    If not, that file is not up to date.

                                    (Your CIDR is 30, so it should skip adding the topology line

                                      I changed cidr to /24 does that change things?

                                        Yes it does. Change it back to 30 and the topology subnet should go away.

                                          Ok but shouldnt it also work with 24?
                                          2.2.6 to 2.2.6 did just fine?

                                            I don't know, but to get to the bottom of your issue, lets just change one thing at a time, or it gets too complicated.

                                            Lets make sure that the openvpn config file in /var/etc is absolutely identical 2.2.6 vs 2.3

                                            Once we get there, we know the GUI and the OpenVPN subsystem are good. About all that is left is firewall rules and route.
