hi,

   Sharing internet access bandwidth between multiple
computers is common today. 

   Usually, bandwidth sharer bought a little router
with NAT/PAT function. After connecting that box to a
ADSL/LAN access link, multiple computer could share a
single access link.

   I heard some company provide prdouct for detecting
number of computers behind NAT/PAT box. 

   Is there any paper or document on how such product
work? where could I fint them ?


  Joe
