The squid log file contains the IP address of clients and could be a
good field to use for counting users. But a NAT shows 1 IP for all

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.
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.
Or there are the logs which contain (or can be configured to record) a
details of *completed* transactions.
