yes, in both directions, but not necessarily in the same mechanism.
nat actually gets my friend more bandwidth out of his cable modem.
his cable modem uses regular old 33.6 dialup to send outbound traffic.
as a result, he gets nice input, but almost no output. what i did for
him was set up a nat gateway on one of his machines (the one to which
the cable modem delivers inbound traffic --- he has only one address)
and set up *that* machine with a default route to his isdn provider.
the result is he gets 112k outbound instead of 33.6, and a big fat
round routing path.
