Abstract:
When an IP address is shared among several subscribers -- with a NAT
or with an application-level proxy -- it is impossible for the server
to differentiate between different clients. Such differentiation is
valuable in several scenarios. This memo proposes a technique to
differentiate TCP and UDP clients sharing an IP address. The
proposed method uses an ICMP Echo Request packet, which allows for
more information about the user mapping to be transmitted than in the
case of using the TCP option - and allows the use with UDP and other
protocols.
