That can be very useful if you are looking for a proxy installed
by one employee or any person in the local network, that's acting
as a proxy to external connections.

>From what I have understood from the original poster what he wants
to find it's the transparent proxy that it's redirecting his
traffic. But if you are finding an application proxy installed
on one of the desktop computers then it could be possible to do
it just using nmap to see what ports are open in all the computers
in the network, or using nessus to find strange programs listening
on strange ports. Nessus can do a great job in portscanning the
network, it has the nmap capabilities and some more techniques to
find open ports.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
