        @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.

                        UPDATE for: Jim Pingle

                        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. :(

                            I was going nuts why my vpn wasnt working anymore... out of options I googled if it was a issue with 2.5.1..

                            well at least I can stop blaming myself :P

                              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!

                                      Any timeframe we can expect a fix to be released?
                                      Neither downgrade nor development version seems a great choice.

                                        I am also just a user who shares your pain, stuck on 2.5.1, any guesses will just be speculation at at this time.
