      Hello,

      Here:http://www.pfsense.org/index.php?option=com_content&task=view&id=40&Itemid=43 we can read:
      "Requires a minimum of three public IP addresses (will be resolved in a future release)"

      And also here:http://doc.pfsense.org/index.php/Configuring_pfSense_Hardware_Redundancy_(CARP)#Overview_of_a_pfSense-CARP_setup wec an read:
      "You need one real IP address for every CARP cluster host. So, if you want to have 2 cluster members, you will need 2 IP addresses for the real interfaces and then an IP for each virtual IP address. So in this case it would amount to 3"

      We can read "(will be resolved in a future release)".

      Is this problem solved with 2.0? If not, can we use NAT on FAI modem and use 3 privates IP addresses for the modem and the two pfsense?

      Thank

        No, it's not a problem, a limitation of how CARP functions. But if you have two public IPs (or NAT on your modem or something else upstream), you don't need the public IPs. Unless you NAT on the modem or have 3 public IPs you can't have stateful failover.

                  Why do you say that?
                  It's not me that write: "Requires a minimum of three public IP addresses (will be resolved in a future release)" ->PUBLIC (http://www.pfsense.org/index.php?option=com_content&task=view&id=40&Itemid=43).

                  With this , we can think that will not work well with private address it's why i ask for a solution…
