      Dear all,

      I was configuring a HA cluster between 2 pfSense Plus 23.01 firewalls and the HA sync part is ok. When I start creating de CARP VIPs on the primary firewall, this configurations are not sent to the secondary firewall and I get some errors.

      Crash report begins. Anonymous machine information:

      No FreeBSD crash data found.

      Any help on this issue? Both firewalls were installed and upgraded to version 23.01. The same configuration works on pfSense 2.6.0-CE.

            Under Diagnostics > Backup & Restore > Configuration History you have the version of the XMLRPC configuration.

            Which versions does it show in master and backup?

                Hello @santanna,

                I am running 23.01 too and have the same issue. It seems to be a an error on the XMLRPC receiving side, when it processes Virtual IPs config.

                My stack trace:

No FreeBSD crash data found.

                Line 399 is around this code part in xmlrpc.php:

                                $vipbackup = array();
                $oldvips = array();
                if (isset($sections['virtualip']) &&
                    is_array($config['virtualip']['vip'])) {
                        foreach ($config['virtualip']['vip'] as $vip) {

                Therefore, I deselected "Virtual IP" under "Select options to sync" and at least it does not generate these crash reports anymore. Of course, it wont sync the VIP settings.

                PS: I opened a ticket at Netgate's TAC Support.

                      As mentioned above it's a bug in 23.01 (#14034)

                      The configuration on the secondary has an empty <virtualips> tag which is tripping up that PHP code. If you go on the secondary and add a dummy VIP, then the sync will succeed and you can delete the dummy entry if the sync doesn't do that on its own.

                        @jimp Yes, once the secondary pfsense has some CARP virtual IP addresses, the error vanishes.

                        Deselecting the "Virtual IP" under "Select options to sync" does not work in the end, if one likes to also use DHCP failover.

                          I added another new CARP VIP, but the interface stays DOWN ?
