ipnet/ipf performance

[Barclay Osborn <bosborn@cyberpass.net>]

Does anyone have experience with the performance degradation induced by
ipnat and ipf?  I'm looking at installing a firewall that'll be doing basic
ipnat (2-6 rules) and a reasonable amount of ipf (30-40 rules) with a peak
of 10Mb/s, ~8Mb/s sustained.  What sort of [x86] hardware would this
require?  What about 9 Mb/s peak, 6Mb/s sustained?  Any help/hardware
recommendations is greatly appreciated.

Thnx in advance,
-Barclay
