> Is that a real, full firewall? Heck no, I'm equally worried about what my systems leak than outside threats, and it does nothing for that. But it is. Even a "full" firewall can't do anything against something on one of the inner host leaking into the outside. Most of the traffic is encrypted, even DNS. So the firewall can't operate on much more than the destination address to decide if a connection should be allowed. If you want more security, you need to secure individual endpoints.
