At minimum a Router or Switch with WCCPv2, plus separate machines for 
client and proxy.

Ideally;
  * at least two router/switch to test the changed code handling 
multiple routers.
  * ability to test both Mask and GRE assignment methods.
  * ability to test a mix of the capability and security settings in WCCPv2.
