FCD-IPM Installation and Operation Manual Chapter 5 Setup Menu

WAN Economy Menu 5-93

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).

ISDN

INTERNET

Any frame starts a

connection

Connection is terminated if

3 frames/60 seconds are

not forwarded

Figure 5-93. Any Frame Starts a Connection

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).
