          We also affected and must roll back.
          Maybe there is a hotfix in the next hours, would be great.

            Good question, i don’t have an alias configured on our WAN-interface. For sure is that NAT is not working on an IP-Alias if used on an != default WAN.

              A hotfix would be awesome! Fingers crossed that Netgate is pushing this issue...

                Yep, it’s the same issue like the link I’ve posted.

                  Same for me. I made and Snaphsot on ESXi and upgraded to 2.6.0-dev. That solved the problem for now. When a hotfix is released for 2.5.1, I will roll back.

                      One point is not really clear to me, is this only an issue if I use gateway groups?

                        Nope, in my case, we don't have gateway groups.

                          hope Netgate can help us with an hotfix.

                            I confirm the same issue here.
                            I have multi WAN setup, after the upgrade all NAT rules ceased to work.
                            I advised a friend not to upgrade, he already did, but isn't suffering from the issue.
                            It seems to be an issue with multi WAN configurations.

                            I had to roll back to previous version.

                                @imanrnm unfortunately, there is no easy way. You have to download the older version and install it. You should also have a backup of your configuration to restore from.
                                I can see another post on your profile saying you've upgraded to 2.6.0, which is still in development and not recommended for production use.

                                  @0x00fe-0 Thank you for reply.
                                  yeah i updated to 2.6.0 and the problem is gone but there is other problems!
                                  for example my speed limiters aren't working now!

                                  i have a veeam backup from 3 days ago before update to 2.5.1, i will try to restore that and see what happens.

                                  all i know is that there is a real mess right now in my network because of a simple pfsense update and i will never again update my firewall right after they release it and will wait at least some days...

                                    we downgrade to 2.5.0, not perfect because of the openssl vulnerability.

                                    And no note in the known issues:

                                      Thanks God I found this post . I was going crazy .
                                      NAT is not broken but suddenly stop working in 2.5.1 .

                                      I must apologize to my certbot server since I'm requesting SSL like there is not tomorrow , and of course, my reverse proxy isn't happy !!!

                                      Any workaround ? not feeling to downgrade or go BETA

                                      cheers ,

                                        unfortunately there is no information about a 2.5.x / -px release.
                                        First time in over 10 years pfSense we can't upgrade the system.
