Not true. I doubt that your links comprise much more than 100Mb or so
(which the existing PIX does OK) and you could certainly make
something like a fast PC perform NAT at *lots* of pps or Kbps.
The only thing with NAT is that you need some memory, but again, the
PIX has a limit of ~16,000 *simultaneous* conversations and doesn't
have much RAM to play with.
