So I setup a test VM (running on ESXi) of ClearOS 6.4 Community. The content filter on this seemed to work well and the proxy ran in transparent mode - so no pesky proxy settings or exceptions.

For a production system, more system resources were needed. This involved buying a dedicated (at least for n…
