Figure 3-10. Sample Network
In the basic example on page 3-14, the administrator configured connection-
rate blocking on port D2. However:

■ The server at IP address 15.45.50.17 frequently transmits a relatively
high rate of legitimate connection requests, which now triggers
connection-rate blocking of the server's IP address on port D2. This
causes periodic, unnecessary blocking of access to the server.
