      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!

          Thanks Steve!

          I sure will test it because I need it :)

            Researching this further I find that although the IPv4 Local network(s) and IPv6 Local network(s) controls are hidden when "Peer to peer (shared Key)" is selected, that is the desired behavior since they make no sense in a peer to peer environment. Whether they are hidden or not, the values are ignored so it really makes no difference.

            There was a display bug in 2.2.x that caused the controls to be displayed.

            So if we are to track down a potential GUI problem, the best approach would be to set up identical server configurations in 2.2.6 and in 2.3 and to then compare the /cf/conf/config.xml files looking at the <openvpn-server>section.

            Is that something you could do?</openvpn-server>

                What about force all traffic trough gateway? This is also hidden in shared key peer2peer.
                Are you sure local networks on SERVER pae should be hidden?

                      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.

                                  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.
