    Has anyone got a VPN to a Draytek working?

      (and Draytek is set to Dial Out, always on)

        I assume the Draytek logs are in reverse order again?

        Did you change to IKEv2 and DH group2 at both ends? pfSense will use IKEv2 if it is initiating and it's set to auto.

        The pfSense failure log will probably be more useful here, obviously we are far more familiar with it.

        However I would say it's most likely an identifier mismatch looking at those logs. IKEv2 has a much larger choice of identifier types. It looks like the Draytek has accepted whatever pfSense is sending as it's showing SA established but pfSene then sends an authentication failure message.

        Since you're using public IPs at both ends if the identifiers are still set to 'my IP' and 'peer IP' that should work.

          Yes both ends were changed, whilst I had the Draytek guy remoted into my Mac
          (The Draytek is set to dial out, not both, if that matters)

          Latest pfsense log entries are:

            Here is the draytek end - there appears to be no peerID setting that end if that might be relevant?

                Ok so not an identifier mismatch, thay are sending their IP as identifier shown in [ ]

                looking for peer configs matching 81.143.205.132[%any]...88.97.12.47[88.97.12.47]

                It still looks like the preshared key is wrong:

                tried 1 shared key for '%any' - '88.97.12.47', but MAC mismatched

                I would test it by using a super simple key that cannot me typo'd or translated like 12345. Move to a better key once it connects with that.

                We can't see the actual encryption settings there, I assume they are under that advanced button. If the HMAC didn't match there I would expect it to fail with a proposal error. It was matching previously for IKEv1 but worth checking.

                  Are you using an especially long PreSharedKey? The maximum ley length is related to auth hash used and you are using SHA1 which limits it to 64B (I think).

                        Hmm, curious.

                        Is this the only tunnel at each end?

                        Does either end have more than one WAN?

                        Can we see the config at the pfSense end?

                          @orangehand said in Has anyone got a VPN to a Draytek working?:

                          looking for peer configs matching 81.143.205.132[%any]...88.97.12.47[88.97.12.47]

                          Ok in fact this could be an identifier issue. It looks like the Draytek is sending 'any' as the identifier for pfSense. What is it actually set to in pfSense?

                          I don't see a place to specify a peer ID in the Draytek settings other than the 'dial-in' section but you might try adding it there.

                              In dial in settings you mean the username field? What would I put there please?

                                Ok the Draytek is sending it's own IP as an identifier but 'any' for the pfSense end. So in pfSense it should be the opposite; 'any' for My Identifier and 'peer IP' for Peer Identifier.

                                But better would be to set an Identifier in the Draytek. The only place in the screenshot I see to do that is the 'Peer ID' filed in the dial-in settings. Try that. See if it changes what is shown in the pfSense logs. You want it to show:
                                looking for peer configs matching 81.143.205.132[81.143.205.132]...88.97.12.47[88.97.12.47]

                                Then set My IP and Peer IP as the identifiers in pfSense to match.

                                    Ah, great. Were you able to get the Draytek to send an IP as identifier or did you have to stick with 'any' as the local identifier in pfSense?

                                      pfSense (my) end I used My identifier: My IP Address and Peer Identifier: Peer IP address
                                      Would you like full screenshots for reference?

                                        Yes please. Might be helpful for someone else in the future.

                                            Hi all

                                            I'm trying to setup a lan-to-lan VPN between Draytek and pfsense using IPSec, but I can't get it to work

                                            I've copied the configuration suggested by orangehand on both ends, with no luck.
                                            The only differences with orangehand's setup is that on the Draytek side I've set the call direction to dial-out, as I need the channel constantly on, and on the pfsense side, in the 'remote gateway' field I've set the external IP of the Draytek, not the FQDN, as I don't have a DDNS set up.

                                            Is there a complete guide on how to set this up, as I can't find a great deal on it online?

                                            Thanks
