You must not follow this list if you think this makes you sound
like an idiot :)

I run natd for my home network connected via cable modem and have
installed it at cutomer sites ranging from 33.6 to T1. While there
*has* to be some speed hit, it has not been noticable for me.

Not sure what "NAT Address Pool" translates to for you, but you can
assign a single IP to the FreeBSD box running nat for a network and
have it take care of address translation for a private IP space lan.

I guess it depends on the size of the internal networks and how much
and what kind of traffic they will generate. All of our networks
are fairly small, 8 to 20 users typically, but the users are mostly
geeks and pretty demanding. No complaints in the last 6 months since
we started using it.
