      @slu said in PFsense CE 2.5.1 NAT broken on interface != default WAN:

      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.

                  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. :(

                                    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.
