From a UAE adsl box:
  0.0.0.0         :80    PFFFFFPPFFFF  FPFP F 2.8/7.2 via:1.1 NC9 (NetCache NetApp/5.2.1D8) agent:NetCache NetApp/5.3.1R1

It's just a normal proxy, except that you don't need to connect to 
it directly. In the UAE case, it does nothing until it sees you 
connect to somewhere on port 80, and then it takes over. All HTTP 
commands it sees are executed by the proxy and never make it out 
to the web site you thought you were connected to.
The fact that you don't need to connect to it, means you don't 
need to configure any proxy in your web browser.

It also means that any tests you do using statProxy (or any other 
proxy tester) on port 80 are invalid. In my proxyTools, mergeHosts 
ignores such tests (and warns you) if it knows there is a 
transparent proxy in the connection, so that you don't stuff up 
your proxy databases.
