redundant firewall

[Julien Cigar]

Hello,

I bought 2 Soekris 6501 in order to setup a redundant firewall (with
Freebsd 10, CARP, and PF). 
Let's say I don't need remote access to each individual boxes from the 
WAN side, I wondered if it's really necessary to bind "real" IPs to 
each interface involved in the CARP alias?

I'm asking this because I don't have enough public IPs...

Thanks!
Julien
