There are five connection modes to choose from as shown below. If you are unsure

of your connection settings, contact your Internet Service Provider (ISP) and you can

enter the necessary information on the Quick Installation Guide (QIG) or print this

page and write the settings for future reference.

All five modes have some common configuration options. The Primary and Secondary

DNS Server settings are required for Static configurations and optional for DHCP and

PPPoE configurations. The Advanced options on the following page can be modified

for any of the five connection modes. You should be able to get the

Primary DNS

and Secondary DNS Servers

settings from your router configuration settings, ISP,

or your network administrator. Only the primary DNS server address is required,

though it is best to have both the primary and secondary addresses.

2.1.2.2 Advanced

The Advanced options apply to all WAN modes.

Use the Default MTU:

This option is enabled by default allowing the router to select

the typical MTU settings for the selected WAN interface. If this option is unchecked,

the router will use the value assigned in the MTU field.

MTU:

The MTU (Maximum Transmission Unit) is a parameter that determines the

largest packet size (in bytes) that the router will send to the WAN. If LAN devices

send larger packets, the router will break them into smaller packets. Ideally, you

should set this to match the MTU of the connection to your ISP. Typical values are

1500 bytes for an Ethernet connection and 1492 bytes for a PPPoE connection. If the

router’s MTU is set too high, packets will be fragmented downstream. If the router’s

MTU is set too low, the router will fragment packets unnecessarily and in extreme

cases may be unable to establish some connections. In either case, network

performance can suffer.

MAC Cloning Enabled:

Some ISP’s may check your computer’s MAC address. Each

networking device has it’s own unique MAC address defined by the hardware

manufacturer. Some ISP’s record the MAC address of the network adapter in the

computer used to initially connect to their service. The ISP will then only grant

Internet access to requests from a computer with this particular MAC address. The

device has a different MAC address than the computer that initially connected to the

ISP. To resolve this problem, enable this option.

MAC Address:

When MAC Cloning is enabled, you can enter in a MAC address

manually in this field or click the Clone Your Computer’s MAC Address button.

Clone Your PC’s MAC Address:

When this button is clicked, the WAN port will use

the MAC Address of the network adapter in the computer that you are using to

access the router.

Multicast Streams

The router uses the IGMP protocol to support efficient

multicasting -- transmission of identical content, such as multimedia, from a source

to a number of recipients. This option must be enabled if any applications on the LAN

participate in a multicast group. If you have a multimedia LAN application that is not

receiving content as expected, try enabling this option.

RIP (Routing Information Protocol)

RIP enables the router to share routing

information with other routers and hosts on the LAN. Enable RIP if the LAN has

multiple routers or if the LAN has other hosts that listen for RIP messages, such as

auto-IP devices or the Windows XP RIP Listener Service. This is (almost) never used

in private homes, only in large corporate networks.

•

RIP Operating mode. This router supports both version 2 and version 1 of the

RIP specification.

V1. Use if none of the routers supports Version 2.

Page 12 of 92

Page 13 / 92

V2 Broadcast. Use if some routers are capable of Version 2, but some are only

capable of Version 1.

V2 Multicast. Use if this is the only router on the LAN or if all the routers

support Version 2.

•

Router Metric. The additional cost of routing a packet through this router. The

normal value for a simple network is 1. This metric is added to routes learned

from other routers; it is not added to static or system routes.

•

RIP Password. This router supports the use of clear-text passwords in RIP

version 2 messages. Only routers with the same RIP password can share

routes via RIP. RIP passwords serve more as a mechanism to limit route

sharing rather than as a security mechanism. You might use RIP passwords,

for example, to prevent routes from one subnet from being seen by a router

on another subnet that has conflicting IP addresses. Enter the password twice

for verification. Leave both password fields empty if RIP passwords are not

used.

2.2

Network Settings

Your internal network settings are configured based on the IP Address and Subnet

Mask assigned in this section. The IP address is also used to access this Web-based

management interface. It is recommended that you use the default settings if you do

not have an existing network.

2.2.1

Router Settings

Router IP Address:

The IP address of the router on the local area network. The

local network settings are based on the address assigned here.

Troubleshoot: In some rare cases, this IP-address will conflict with the address (or

rather address range) of the WAN side. This situation occurs if a similar device like

this (e.g. a router) is placed in front of this device, causing the same IP-subnet on

both WAN and LAN on this device. In that case: Change to 192.168.100.1 and also

change the DHCP IP-range (a field further down) accordingly: exchange 176 with

100.

Subnet Mask:

The subnet mask of your router on the local area network.

Local Domain Name:

This entry is optional. Enter a domain name for the local

network. Your LAN computer will assume this domain name when it gets an address

from the router's built in DHCP server. So, for example, if you enter mynetwork.net

here, and you have a LAN side laptop with a name of “chris”, that laptop will be

known as chris.mynetwork.net. Note, however, the entered domain name can be

overridden by the one obtained from the router's upstream DHCP server.

Enable DNS Relay:

When DNS Relay is enabled, the router plays the role of a DNS

server. DNS requests sent to the router are forwarded to the ISP's DNS server. This

provides a constant DNS address that LAN computers can use, even when the router

obtains a different DNS server address from the ISP upon re-establishing the WAN

connection. You should disable DNS relay if you implement a LAN-side DNS server as

a virtual server.

2.2.2

RIP (Routing Information Protocol)

Enable RIP:

Check this options to enable the

Routing Information Protocol.

This

protocol is used with multiple routers to broadcast routing information. Enable RIP if

required by the ISP, if the LAN has multiple routers, or if the LAN has auto-IP

devices.

Accept updates (from WAN):

Enable this option if required by your ISP.

Otherwise, for security reasons, leave disabled.

RIP Operating Mode:

Select which version of the

Routing Information Protocol

to

run. Use

V1

if none of the other routers support V2. Use

V2 Broadcast

if some, but

not all, of the other routers are capable of V2. Use

V2 Multicast

if this is the only

router on the LAN or if all the routers support Version 2.

Router Metric:

The additional cost of routing a packet through this router. The

normal value for a simple network is 1. This metric is added to routes learned from

other routers; it is not added to static or system routes.

Act as default router:

Make this router the preferred destination for packets that

are not otherwise destined.

RIP Password:

RIP Version 2 supports the use of a password to limit access to

routers through the RIP protocol. If the ISP or other LAN router requires a RIP

password, enter the password here.

2.2.3

DHCP Server Settings

The DHCP section is where you configure the built-in DHCP Server to assign IP

addresses to the computers and other devices on your local area network.
