Hello,
I have a certain task to count the number of unique devices
connected (Could be also transparently) to squid proxy server. While
the users can be on different networks and behind NAT.
Is it possible?
No, not really. As Marcus said NAT erases information. As does any
HTTP multiplexing being performed by downstream proxies.
Is it possible for squid to identify NAT?
What is the best approach of implement it?
Squid provides a management report "client_list" with all recently
seen client devices. It is reliable for the *currently* connected
clients, but once a client disconnects entries are discarded relative
to how much traffic they have used.
Does this report also words behind NAT? can you refer me to more
descriptive information about "client_list"?
Or there are the logs which contain (or can be configured to record) a
details of *completed* transactions.
