6.1 Ways of Reducing Operating Costs
The sections below contain information on how to reduce operating costs. At
the end of each section, you are directed to the menu that allows you to set
up these parameters.

EMAND
Connection on Demand activates the link only when traffic needs to be sent.
The user can define conditions for starting and terminating a connection. In
this way, the link is not constantly up. Once a connection is established, you
are able to define when to terminate and restart the connection. Alternatively,
connection and disconnection can be done manually. This ensures that a
connection is only established when traffic needs to be sent on the link.
To access the Connection on Demand menu:
1. From the Advanced menu, select option 1. The Setup menu appears.
2. From the Setup menu, select option 5. The WAN Economy menu
appears.
3. From the WAN Economy menu, select option 2. The Connection on
Demand menu appears.
4. Follow the on-screen instructions to set the Connection on Demand
parameters.

ILTERING
Filtering allows the user to decide which traffic the Internet Access Router
should allow to enter and exit the LAN. Limiting unnecessary traffic saves
bandwidth and improves security of the LAN. However, care should be taken
to minimize the number of filters defined. Too many filters can reduce the
performance of the Internet Access Router. Filtering can be implemented
through two modes: blocking or forwarding.
When a filter is in the blocking mode, the Internet Access Router tests
each packet of data that is sent to or from the LAN. If the packet passes the
test, it is blocked from entering or exiting the LAN. In the forwarding mode,
passage is allowed if the packet passes the test.
For a more detailed description and instructions on implementing
Filtering, refer to
