Windows doesn't use the tcp timestamp field by default, unless a
connection is started with it with the field in use. So for that to
work, you would have to flood/scan their internal network with packets
that are using the timestamp field and catch the results. Then, by
comparing the drift in the timestamps you should be able to tell how
many devices the NAT is translating for.
