      Hi,

      I have 2 external Pfsense firewalls all working well and using CARP, however when i set up two more pfsense boxs inside the network when i add one CARP address, the system still works but when i add two CARP address's, it causes the network to slow and not work correctly.

      The set up is as follows:

      External CARP
                                                                xx.xx.xx.xx
                             WAN IP xx.xx.xx.xx                                 WAN IP xx.xx.xx.xx
                             LAN IP  10.10.1.21                                  LAN IP 10.10.1.22
                                                             Internal CARP
                                                               10.10.1.23

      Web Server1      /      Web Server2

      CARP 10.10.1.28
                               WAN IP 10.10.1.29                             WAN IP 10.10.1.30
                                LAN IP 10.11.1.1                                LAN IP 10.11.1.2
                                                           CARP 10.11.1.3

      Internal Network

      So as soon as i set up both CARP devices on the second set of firewalls this is when the problems start. I can nowever set up the one CARP address eg. 10.10.1.28 and this seems to work fine, its only when the second is added i get issues.

      Thanks

        Figured out where i was going wrong on this - on the first set of firewalls i was using VHID 1 /2 and the same for the second internal firewalls, silly mistake - after setting the internal to VHID 3 /4 it is all working correctly. ;D
