CARP and Routed Real IP Subnet



  • Hi Guys

    I'm looking at using PFSense in a CARP setup.

    I currently have a /27 subnet routed to me. I'm using monowall at the moment, and I have this /27 subnet on one of my OPT interfaces. I also have a LAN interface.

    Can I use CARP and still have this /27 routed to me?

    Do I simply use 3 of the /27 IP addresses to do the CARP setup?

    For example:

    PFSense Master - OPT1 Interface = xxx.xxx.129.2/27
    PFSense Backup - OPT1 Interface = xxx.xxx.129.3/27
    CARP VIP = xxx.xxx.129.1/27

    And then the CARP VIP becomes the Default Route for my server? Have I got this right?

    Thanks
