s

- A measurement of the preference of a route. Typically, the lowest

metric is the most preferred route. If multiple routes exist to a given

destination network, the route with the lowest metric is used.

IGMP (Internet Group Management Protocol) Multicasting

The FiOS 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 email

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 FiOS Router. When an

application running on a computer in the network sends out a request to join

a multicast group, the FiOS Router intercepts and processes the request. If the

FiOS Router is set to “Minimum Security” no further action is required. However, if

the FiOS Router is set to “Typical Security” or “Maximum Security,” the group’s IP

address must be added to the FiOS 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.

Domain Routing

Domain routing is used in multi-router local network configurations. Normally,

to access 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

appropriate check box) allows the user to access to the computer by name

(as well as IP address).

IP Address Distribution

The FiOS Router’s DHCP server makes it possible to easily add computers

configured as DHCP clients to the network. It provides a mechanism for

allocating IP addresses to these hosts and for delivering network configuration

parameters to them.

For example, a client (host) sends out a broadcast message on the network

requesting an IP address for itself. The DHCP server then checks its list of

available addresses and leases a local IP address to the host for a specific period

of time and simultaneously designates this IP address as “taken.” At this point,

the host is configured with an IP address for the duration of the lease.

The host can choose to renew an expiring lease or let it expire. If it chooses to

renew a lease, it will also receive current information about network services,

as it did with the original lease, allowing it to update its network configurations

to reflect any changes that occurred since it first connected to the network. If

the host wishes to terminate a lease before its expiration, it can send a release

message to the DHCP server, which will then make the IP address available for

use by others.

The FiOS Router’s DHCP server:

Displays a list of all DHCP hosts devices connected to the FiOS Router.

s

Defines the range of IP addresses that can be allocated in the network.

s

Defines the length of time for which dynamic IP addresses are allocated.

s

Provides the above configurations for each network device and can be

s

configured and enabled/disabled separately for each network device.

Can assign a static lease to a network computer so that it receives the same IP

s

address each time it connects to the network, even if this IP address is within

the range of addresses that the DHCP server may assign to other computers.

Provides the DNS server with the host name and IP address of each computer

s

connected to the network.

Complete the following fields:

3.

Start IP Address Range, End IP Address Range

s

- determines the number

of hosts connected to the network in this subnet. “Start” specifies the first IP

address assigned in this subnet and “End” specifies the last IP address in

the range.

Subnet Mask

s

- used to determine to which subnet an IP address belongs. An

example of a subnet mask value is 255.255.0.0.

WINS

Server

s

- The WINS (Windows Internet Naming Service) server

determines the IP address associated with a network device.

Lease Time

s

- each device will be assigned an IP address by the DHCP server

for a limited time (“Lease Time”) when it connects to the network. When the

lease expires, the server will determine if the computer has disconnected

from the network. If it has, the server may reassign this IP address to a newly-

connected computer. This feature ensures that IP addresses not in use will

become available for other computers on the network.

Provide host name if not specified by client

s

- when activated, the FiOS

Router assigns the client a default name if the DHCP client does not have a

host name.

in the DHCP Connections screen. The “DHCP

Connection Settings” screen appears.

Enter a host name for this connection.

Enter the fixed IP address to assign to the computer.

7.

Enter the MAC address of the computer’s network card.

Click the

Apply

to save changes.

Note:

A device’s fixed IP address is actually assigned to the specific network

card’s MAC address installed on the network computer. If this network card is

replaced, the device’s entry in the DHCP Connections list must be updated with

the new network card’s MAC address.

To remove a host from the table, click the appropriate “Delete” icon in the

Action column.
