      switch to TAP-mode.

      WHAT??

      Now you wanting to bridge vs route? I'm done if you can not follow the simple instructions given in the link - have fun!

      I tried, believe me! Right now I am in telco with a technician from the router-support and connection works after adding a static route. It isn't really elegant right now, I agree ...

          Solved now, I had missed the "Client Specific Overrides" part .. my mistake, sure.
          Now that was a big circle walked .... sigh
          Thanks again.

          Now to cleaning up my FW-rules, and documentation ... next sites are coming.

                Ok great - now I would suggest you turn off compression, looks like you have it set on? And your using sha1 vs 256, those are not defaults?? And don't see them mentioned anywhere in the link - so why would you have changed them? Are you using an older version of pfsense?

                Google VORACLE for info for the compression info.

                  The remote site seems to enable LZO comp even when we set it to "disabled" there, so I enabled it as well.
                  SHA1 is the only choice he has, we now run AES-256-CBC (different from above config from yesterday).

                  I browsed the logs for OpenVPN on pfsense (2.4.4p2 btw) and changed settings which triggered warnings.

                    Well have to live with the limitations of the other end - replace it with pfsense ;)

                      I disabled comp (chose 1st entry "Disable Compression"), he disabled. I push compress options there now and I get a ping and these logs:

                      SENT CONTROL [aba_n_ka]: 'PUSH_REPLY,route 192.168.160.0 255.255.255.0,compress ,route-gateway 10.1.160.1,topology subnet,ping 10,ping-restart 60,redirect-gateway def1,ifconfig 10.1.160.3 255.255.255.0,peer-id 1,cipher AES-128-GCM' (status=1)
                      

                      Otherwise it seems rather safe to me. The clients are only allowed to one separate VLAN behind pfsense etc etc

                      The guy understands all the fuzzing around, but I assume he mistrusts me and pfsense a bit now ;-)

                        Why are you redirecting gateway? That is normally not done in a site to site setup.

                          A leftover from my desparate debugging. Thanks for spotting, disabled it now (was in the CSO).
