Hi Adam, Yeah, that is pretty much how I see it having to happen also. I have done that in the past, I was just very curious if it could be done differently. LOL Curiosity killed the cat. LOL

The default gateway of your clients is the virtual IP. Depending on witch box is the master it takes over the virtual IP. There is also a dedicated sync interface that will keep everything in check and updated. I have a CARP setup running. Multiple interfaces,DHCP,IPsec, ect all fail over within seconds. In my case i used 3 IP's for each carp interface i wanted to use. (One Virtual, Two for each interface on the Master and Backup) Not sure if you can use less.

So on a pair of failover ASA's I only need to use either 1 or 2 IP's (if I want to) to handle moving the gateway IP between the pair, including setting the mac address. I have been playing with pfSense to see if I set CARP to try to do the same thing, but so far I haven't seen a way to do it or I am just missing it. It seems like CARP acts more like HSRP in the fact it needs 1 IP set on the interface of each pair and then will only move any IP I set as a CARP IP. Which is they way I understand HSRP works. Now with VRRP I only need 2 IP's total to handle failover and with the ASA failover I can reduce it down to a single IP. Any thoughts or suggestions on if pfSense can do this or how I would make it do it? I am curious to see if it can be done.
