IPFW Failover possible with IPFW?

Hello all,

is there a way to get some kind of failover working with two hosts running the ipfw firewall? From what I have read there is no such thing as pfsync for ipfw (so states would be lost at failover).

But is there still another way to achieve failover with ipfw? As I also want to use NAT64, my only alternative would be to use OpenBSD/pf, but then I would not be able to run my firewalls in a Jail.

Cheers
