4. In

End IP Range

, enter the ending IP address of the range of addresses from which the DHCP server

will lease to requesting DHCP clients.

This range definition should consider the following address restrictions:

•

The range of IP addresses may extend over only one IP subnet.

•

The maximum size of the address pool that may be managed by the DHCP server is 64.

Therefore, the range of addresses must not exceed 64.

•

The range of IP addresses should not include any IP address maintained internally by your

SpeedStream device for other purposes. This includes the device’s LAN-side static IP address, as

well as the Default Router IP address, Primary or Secondary DNS IP addresses, and Primary or

Secondary Relay IP addresses

.

•

Commonly used non-Internet routed IP address ranges include:

10.0.0.0

- 10.255.255.255

172.16.0.0

- 172.31.255.255

192.168.0.0

- 192.168.255.255

5. In

IP Netmask

, enter the IP subnet mask that corresponds to the range of IP addresses defined

above.

6. In

Default Gateway

, do one of the following:

•

Enter the IP address of a default gateway, or router, to be provided to DHCP clients.

•

Click

Self

to specify that the SpeedStream Router is to be used as the default gateway.

7. In

DNS Server (primary)

, do one of the following:

•

Enter IP address of the primary Domain Name System (DNS) server to be provided to DHCP

clients. A DNS server may be used by clients to resolve domain names to IP addresses.

•

Click

Use WAN

to specify that the address of the DNS server provided by your ISP is provided to

DHCP clients on the LAN.

8. In

Domain Name

, optionally enter the DNS domain name for the DHCP server resident on your

SpeedStream device. This value must be entered as an alpha-numeric string.

9. In

Lease Time

, do one of the following:

•

Enter the period of time an IP addresses leased from the DHCP server is valid. At the end of the

lease period, the DHCP client will transmit a request to the server to extend the lease, at which

time the server will extend the lease period of the IP address assigned to the client. If the lease

period expires without the server receiving a request from the client to extend the lease, the server

will assume the client’s connection no longer exists. The server will release the IP address

assigned to the client and return the address back to the pool of available addresses. (If you select

this option, you must specify a DNS Server.)

•

Click

Infinite Time

:

Leaves the lease time open-ended, preventing the server from releasing the IP address.

Static Routes

The SpeedStream DSL Router directs data traffic by “learning” source and destination information, then

building a routing table. In some cases, network mappings cannot be learned because of incompatible

addressing schemes. Sometimes a different source and destination path may be desired over the learned

paths for example when your ISP assigns you a static route. In these situations, Static Routes

can be

configured to map a desired pathway.

Use the static routes advanced option to configure static routes to remote equipment. Static routing

allows a pre-defined route to be set for the transmission of data. Static routes take precedence over all

dynamic routing options and also provide enhanced security over dynamic routing.

To configure a static route:

1. Select

Setup>Static Routes

from the left navigation pane of the Web interface. This displays the

“Static Route Configuration” window.

2. Under

Add Route

, type the IP address of the destination device in the

Destination

box.

3.

Type the net mask of the destination device in the

Net Mask

box.

4.

Optionally, type the IP address where the data packets will be forwarded in the

Next Hop

box.

5.

Select a connection type from the

Interface

drop-down menu. This is the interface that will forward

the packets.

6. Click

Apply

. The system responds by adding your new route to the routing table.

7.

You can repeat this procedure for each static route you wish to add.

Note:

To edit a static route, click the

Edit

column for the static route you want to edit.

Note:

To delete a static route, click the

Delete

column for the static route you want to delete.

RFC2684

The SpeedStream Router supports two basic types of connections: Point-to-Point (PPP) and RFC2684.

By default, RFC2684 connections rely on a server located on the Wide Area Network (WAN) to supply the

Router a dynamic IP address and other IP-based configuration parameters for the Router’s WAN-side

interface. To accomplish this, the Router executes a Dynamic Host Configuration Protocol (DHCP) client

associated with the WAN-side connection. This client, in turn, communicates with the DHCP server

located on the WAN.

Under some circumstances, this automated procedure may not be desirable or even possible. In such

situations, you will need to disable the DHCP client on the router and manually define the required IP

configuration parameters, as supplied by your service provider.

To configure RFC2684 functionality:

1. Select

Setup>RFC2684

from the left navigation pane of the Web interface. This displays the

“RFC2684 Configuration” window.

2.

Select the connection you want to configure from the

Connection

drop-down menu.

3.

Select one of the following from

DHCP

:

•

Enabled

Enables the Dynamic Host Configuration Protocol for the selected connection.

•

Disable

Disables the Dynamic Host Configuration Protocol for the selected connection.

4. In

IP Address

, enter the IP address to be used for the WAN-side of the Router, normally obtained

from a DHCP server located on the WAN.

5. In

IP Netmask

, enter the netmask corresponding to

IP Address

.

6. In

Default Gateway

, optionally enter the IP address of a router located on the WAN to be used as the

"gateway" to the WAN.

7. In

DNS Server

, optionally enter the IP address of a DNS server located on the WAN to be used to

resolve domain name/IP addresses.

8. Click

Save

Configuring Network Settings

This section contains details for configuring network-related information. The network settings options are

listed below.

RIP

Activate and control RIP functionality. Using RIP, the Router is able to determine the

shortest distance between two points on the network based on the addresses of the

originating devices.

Port Forwarding

Control WAN-side access to LAN-side servers through private IP addressing.

UPnP

Configure and control UPnP interoperability and security.

Bridge Mode

Configure the Router as a true WAN/LAN bridge.

Server Ports

Specify server ports used by common applications such as HTTP (Web site traffic), FTP,

and Telnet.

Dynamic DNS

Set up Dynamic DNS. Dynamic DNS translates IP addresses into alphanumeric names.

For example, an IP address of 333.136.249.80 could be translated into siemens.com.

RIP (Routing Information Protocol)

By default, the SpeedStream Router does not support routing protocols. However, support for the Routing

Information Protocol (RIP), versions 1, 2 or 1 and 2, can be activated. This support may be configured for

any WAN connection currently configured or for the LAN in general.

Using RIP, the Router is able to determine the shortest distance between two points on the network

based on the addresses of the originating devices. RIP is based on distance algorithms to calculate the

shortest path using information in the routing table. The shortest path is based on the number of hops

between two points.

To use the RIP option:

1. Select

Setup>RIP

from the left navigation pane of the Web interface. This displays the “RIP

Configuration” window.

2.

Select one of the following options from under the

RIP Version

heading next to the connection of

your choice:

•

1

: Provides essential RIP packet formatting for routing information packets.

•

2

: Provides enhanced packet formatting for routing information packets by providing the following:

IP address, subnet mask, next hop, and metric (shows how many routers the routing packet

crossed to its destination.

•

1&2

: A combination of both types of RIP packets.

3. Select an

Active Mod

e checkbox next to a corresponding connection to enable it.

4. Click

Apply

. This displays the “Your Settings Have Been Saved” window.

5. Optionally, click

Reboot

if you wish for the settings to immediately be implemented. The system

responds by restarting your Router.
