Static Defense Example: Blocking TCP Connection from a Specific Host

This example demonstrates how to set up a new rule to block a host with a specific IP address to connect
to UCM using TCP connection. In the following figure, 192.168.40.142 is the host IP address and
192.168.40.131 is the UCM's IP address. Port 8089 on UCM is used for HTTP server/web UI access. This
setting will block host on 192.168.40.131 to access UCM port 8089 using TCP connection.

After saving and applying the change, host 192.168.40.142 will not be able to access UCM web UI anymore.
