If we didnвЂ™t do both then a proxy could exist on your network in the private IP ranges (which are allowed) and therefore have internet activity. These technologies come inbuilt with Windows. This tutorial suggests using Windows Firewall managed through Active Directory to block all internet IP addresses in additional to enforcing a non-existent proxy.
