Hi,

Two months back when i was configuring an ADSL router at a clients site, the client questioned me about the the working of the ADSL router. I explained to him what was ADSL and how we (ISP) used NAT to dynamically allocate IP addresses.

One month later i recieved a complaint, and when i went to attend it---- everything was fine!!. Now when i met their admin. (the person who registered the complaint) he told me that he needed Live IPs to maintain the security of his organisation.

Still even today, i wonder how the network would become more secure when Live IPs are used instead of dynamic NAT??
