Actiontec Broadband Router User Manual

When adding a routing rule, the following parameters must be specified:

•Rule Name- Select the type of network from the drop-down list.

•Destination - The destination is the destination host, subnet address, net- work address, or default route. The destination for a default route is 0.0.0.0.

•Netmask - The network mask is used in conjunction with the destination to determine when a route is used.

•Gateway - Enter the Router’s IP address.

•Metric - A measurement of the preference of a route. Typically, the lowest metric is the most preferred route. If multiple routes exist to a given destina- tion network, the route with the lowest metric is used.

IGMP Multicasting

The Router provides support for IGMP multicasting, which allows hosts connected to a network to be updated whenever an important change occurs in the network. A multicast is simply a message that is sent simultaneously to a pre-defined group of recipients. When joining a multicast group, all messages addressed to the group will be received by the user, much like when an E-mail message is sent to a mailing list.

IGMP multicasting enables UPnP 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.
