Product as winroute and one spare NIC card on PC will do the trick.
Winroute comes with build in FW as well so maping "the new network" behind
it is limited.

1. I think, you monitor the network traffic and see which authorized
machines are generating the most of the traffic. And hen you can conclude
who is running the proxy server on their machines.


That could be perfectly a router to other network, and maybe you can't
see behind that device.

2. Or you can use npulse to check all the machines in ur LAN and see
which ports are open on these machines.


This approach is defective because if the transparent proxy is
implemented in the router or firewall then you will only see
port 80 open, if the administrator has done his work well then
the port 8080 or 3128 will be closed for the internal network.


Thanks

Perhaps if you are on linux you can use nmap to scan your whole subnet
and
output the scan to a text file then you can grep it for the word proxy (
means you gotta be root and do an -sV ) correct me if im wrong.

Dear all,

Thanks for your suggestions. May be I am not able to define my question
properly.

This problem is strictly with in company internet access firewall and
in
the
LAN only. In a company, policy for Internet access says it is through
IP
only. The others can not browse the internet. This policy is
implemented
on
firewall. Few smart guys have installed free proxy server running on
non
default ports and distributed the internet access to their friends. The
firewall sees the traffic coming from the authorized IP and does not
stop
them. We want to know who has installed proxy on there machine.

I hope, I am able to clearly define my question. Thanks

I'm not sure of a tool, but simply scanning your network for TCP/8080
or
TCP/80 or TCP/8000 may give you the results you are looking for.
Simple
NMAP
would work.

Dear all,

I am looking for a tool to find the hidden web proxy server in my
local
network.

Any hint will be useful.

with regards
