CARP VIP doesn't respond to any traffic in version 2.2



  • We have a pair of pfSense boxes used as HA, we recently upgraded the secondary to 2.2, then we found the box fails to respond to any traffic going to the its CARP VIP(the box is configured as master for that VIP). We tried 2.2.1, 2.2.4, 2.2.6, all these three 2.2.x versions of pfSense have same problem for us, but 2.0.1 and 2.1.5 worked fine.

    The two pfSense boxes are two blades on IBM blade server. Tcpdump didn't get anything, it looks like that the traffic just silently gets ignored on that box.

    Anybody had similar issue? let me know any info you want or questions you have. appreciate for your help.
