I am seriously considering getting two pfSense boxes with CARP
failover.
Does this require identical hardware on the two systems (or
perhaps just
identical network card setups)?
I don't think this is a requirement for CARP.
This is not a requirement, however, if the master is gigabit make sure
the backup has gigabit too.
I think you should examine how CARP works on your routers and how it
works in pfsense.
In pre 2.0 version, PFsense CARP has a (fixed) different zone for each
interface, so if an interface goes down it switches only that interface,
and traffic bind to that interface becomes unreachable.
It is useful only if a machine goes down, not if an interface goes down.
If you actually switch all interfaces when one goes down, you can't do
on pfsense.
Don't know about 2.0 (but I suppose to be the same).
I feel this to be a great limitation of pfcarp implementation in pfsense.

Tonino
