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 UCM6100 using TCP connection. In the following figure, 192.168.40.142 is the host IP address and
192.168.40.131 is the UCM6100’s IP address. Port 8089 on UCM6100 is used for HTTP server/web UI
access. This setting will block host on 192.168.40.131 to access UCM6100 port 8089 using TCP
connection.

After saving and applying the change, host 192.168.40.142 will not be able to access UCM6100 web UI
anymore.
