Chapter 8 Using Advanced Settings
IGMP multicasting enables UP n P capabilities over networks and may also be useful
when connected to the Internet through the Router. When an application run-
ning on a computer in the network sends out a request to join a multicast group,
the Router intercepts and processes the request. If the Router is set to “Minimum
Security” no further action is required. However, if the Router is set to “Typical
Security” or “Maximum Security,” the group’s
IP address must be added to the
Router’s “Multicast Groups” screen. This will allow incoming messages addressed to
the group to pass through the firewall and on to the correct networked computer.
1. Select Routing in the Advanced screen.
2. Activate the “Internet Group Management Protocol” check-box.
3. Click OK.
Domain Routing
Domain routing is used in multi-router local network configurations. Normally,
to accesss a device connected to one router from another router on the network,
its
IP address must be used. Activating domain routing (by clicking in the appro-
priate check box) allows the user to access to the computer by name (as well as IP
address).
Network Objects
Network objects is used to define a part of the Router’s network (a group of
computers, for example) by
MAC addresses, IP addresses, and/or host names. The
defined part becomes a “network object,” and settings, such as configuring system
rules, can be applied to all the devices defined as part of the network object at once.
For example, instead of setting the same website filtering configuration to five com-
puters one at a time, the computers can be defined as a network object, and website
filtering configuration can then be applied to all the computers simultaneously.
Network objects can be used to apply security rules based on host names instead
of
IP addresses. This may be useful, since IP addresses change from time to time.
Moreover, it is possible to define network objects according to MAC addresses, mak-
ing rule application more persistent against network configuration settings.
