Example 2:

To lower expenses, FCD-IPM is configured so that a line to the Internet is activated when there is a need to connect to the Internet and terminates when no frames are transmitted for 60 seconds. Therefore the following must be defined:

•Start Connection is any frame to forward

•Terminate Connection is no frame to forward for 60 seconds (see Figure 5-93).

Example 3:

The company management wants to allow the PC with the IP address 1.2.3.4 only access to the Internet. In addition, the connection to the Internet is to be terminated if 3 frames every 60 seconds are not transmitted from this PC.

Therefore the following must be defined:

•Start connection must be specific frame to forward. A filter which allows only frames from the 1.2.3.4 IP address must be defined.

•Terminate connection must be no specific frame to forward. A filter which counts only frames from the 1.2.3.4 IP address must be defined. In addition the rate must be defined at 3 frames/60 seconds (see Figure 5-94).
