When the original routing, you are basically calling your TCP / IP a wrong street stack for a destination; Many systems provide simple syntax for it, but it is your best bet for empty routing of a host or network under Windows, sending the packet to a non-existent gateway. The plus-side for zero-routing is that it is very simple, fast, and uses the path in the TCP / IP stack which is highly optimized for heavy lookup.

You can use firewall rules to leave packets, but you can use your firewall for 'more important' policy decisions, and your firewall tables with a list of hosts If you do not want to talk to any of the time you can interpret, then firewall rules may be more difficult to inspect; Or, you may have to enable firewalls, you may have to take a performance penalty that you do not want otherwise.
