      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.

            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.
                    https://www.openssl.org/news/vulnerabilities.html

                    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.

                              No workaround or quick fix. See latest reply from Jim Pingle here: issue 11805
                              The issue seems to be "in kernel" so bummer, we need to wait it out.

                                2.6.0 snapshots are currently working correctly, and the fix was checked into RELENG_2_5_0. Whatever release happens next will behave correctly either way (e.g. a 2.6.0 release or a 2.5.x point or patch release).

                                  I have the same issue. We have nat rules on a multiwan configuration. Upgrading from 2.5.0 to 2.5.1 nat rules on wan1 works but those on wan2 are not working.

                                  we had to restore from backup. :(

                                      Think this was the fix.

                                          since the kernel must be rebuild, no chance to fix this with the patch package.
                                          We also wait for a new pfSense release since we have issues with this bug.

                                            @infosamu-it since netgate hasn't released the build tools, not much we can do but wait for the next release AFAIK. 2.6.0 is an option but there are a few issues with that I know of

                                            kernel panics #11839
                                            counters 0/0 #11775
                                            Also rate limiting seems broken as per another user. maybe related to #11775.

                                            pfsense fun!
