      That makes sense โœ‹

      -so, have you ever considered IPsec?
      I personally hate the L2TP old and rigid protocol and it is no longer so secure.

        @DaddyGo Actually I did not think but we are in a transition period now. That's why we manage it for now. Trying for a deep-rooted job because of a minor problem also requires effort. Otherwise, L2TP started to be troubled as you said.

          I understand...

          We have long been doing the following:

          central pfSense OpenVPN server (headquarter) and smaller pfSense-enabled devices at employee endpoints as OpenVPN clients
          https://pcengines.ch/apu4d4.htm (110-130USD)

          so it doesn't matter what OP system is running on the client side (employees) (macOS, Windows, Linux)
          since both endpoints have pfSense and OpenVPN

          Cats bury it so they can't see it!

            don't worry, I rarely see L2TP posts on the forum, probably someone will come who has similar problems...

            now you have to wait a bit...

              Unfortunately, it is now. By the way, I am looking for the solution. There is no problem with the Radius server either in the manual user. It's annoying.

                  "the log shows that the connection is basically not working"

                  I would do that:

                  try to build a whole new test connection just for the sake of the test
                  which is by no means related to previously configured L2TP connections

                  of course on the updated system

                  this basically filters out that importing existing settings into the newer environment is causing the error

                  or L2TP really doesn't work on your system (under the new release) - +++I do not believe this โ˜บ

                  what L2TP client is on the other side software configured or hardware dependent?

                  I am thinking of this here:
                  https://www.thegreenbow.com/index.html
                  (in the past we have used this client for L2TP)

                  PS:
                  the settings stored in XML may not be realized in the new environment

                  +++edit:

                  just notice the end of the description:
                  https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/l2tp-ipsec.html

                  +++edit: (pay close attention to this)

                        okay I'm running out of ideas...
                        let's see @jimp can help you, if he are currently available...

                        I note, I really used L2TP a long time ago, but now I'm interested in this theme (just for the sake of curiosity)

                        I just see the despair in your writing, ergo I want to help...
                        never give up, colleague...
                        now I have to go, because my wife opened the weekend red wine

                                    I started to tamper with the problem and I could not understand what to do with this method. I understand that I just need to delete the secret key. Is it correct? If it is true, it does not work, unfortunately.

                                      I solved the problem. After installing the patch, I added Pre Shared Key on the IPsec side and the problem was resolved.
