Subject: Identifying computers behind a NAT
Date: Mon, 07 Oct 2002 20:07:35 -0500 [thread overview]
Message-ID: <20021008010735.8144.qmail@mail.com> (raw)
Hi,
For billing and licensing reasons in our product, I need to be able to identify machines when they connect to our server...
The issue that we have is that these machines may be behind a NAT firewall and we dont see the real IP of the machine...
Is there any way at all to identify a socket connection as belonging to a certain machine other than just IP address? For example, would I be able to look at the TCP packets acknowledge numbers and that in combo with the IP would give me some idea of the machines behind the NAT?
Thanks
Lyle
