Public ip address as carp
i have try to use a public ip address for carp. but the system say "Sorry, we could not locate an interface with a matching subnet for X.X.X.X/32. Please add an IP alias in this subnet on this interface."
i have only one public ip address and this public ip is routed to pfsense over a transfer network. how can i use the public ip address.
is it ok to apply the public ip as alias ip on both firewall? the ip will be routed only to the active firewall.

Until we get carpdev (probably when pfSense goes to FreeBSD 10 as a base), you need a minimum of three public IPs to make a failover cluster. One on each firewall and one or more shared IPs.
its a goog idea to use alias ip with /32 on both server? the routing goes every time to the active firewall. if not we must nat on the upstream firewall.
