Embedded NetBSD Firewall

[Steve <pf%unliketea.com@localhost>]

Evening Guys,

I am looking for a router or device I can run a netbsd firewall on.  
Preferably, something that supports carp so I can bond 2 of them.

For those that ask why:
Because i want to.
Want a small low power device.
I really like pf.
HA with carp would be fun to do.

Thanks
Steve
