You could use nat, do it selectively. So will not be able to bypass the proxy for outbounds or unable to navigate, also the port usage is through nat, and  if no nat, they  can not see anything behind the proxy. If this doesn't work, also you can monitor your network  with some tools as wireshark, and blocks the proxy's packages manually
