.

•

Username:

Enter the username for your DDNS account.

If you have not previously registered a host name, you can click

link, and then continue through all of

the steps.

•

Password:

registered with your DDNS provider. For example, if your host name is

myhouse.dyndns.org

, then enter

myhouse

in the first field,

dyndns

in the

second field, and

org

in the last field.

The following read-only information appears:

•

The current WAN IP address for the interface.

Because it is dynamic, this setting will change.

•

to save your settings, or click

Cancel

to undo them. Any unsaved changes are abandoned.

Perform the following tasks:

•

To configure static or dynamic routing:

Click the

IPv4

or

IPv6

tab, and

then enter the settings. See these topics:

-

Configuring Dynamic Routing, page 58

-

Configuring Static Routing, page 59

•

To view current data:

Click

Configuring Dynamic Routing

Enter the settings for

dynamic routing

by using

Routing Information Protocol

(RIP)

(see the glossary for more information).

Dynamic Routing for IPv4:

Click the

IPv4

tab, and then enter the settings described below.

•

Working Mode

: Choose one of the following options.

-

Gateway:

Choose this mode if the router is hosting your network’s

connection to the Internet. This is the default setting.

-

Router:

Choose this mode if the router exists on a network with other

routers, and another router acts as the network gateway to the Internet.

In Router mode, Internet connectivity is available only if you have another

router that functions as the Gateway. Since firewall protection is

provided by the gateway router, disable this router’s firewall. See

Configuring the General Firewall Settings, page 99

.

•

RIP:

Routing Information Protocol allows a router to exchange its routing

information automatically with other routers, and to dynamically adjust its

routing tables as network changes occur. RIP prevents routing loops by

using a hop limit. To enable this option, select

Enabled

. Otherwise, keep the

default setting,

Disabled

. If you enable this feature, also configure the

following settings:

•

Receive RIP versions:

Select the RIP protocol for receiving network data:

None

,

RIPv1

,

RIPv2

, or

Both RIP v1 and v2

.

RIPv1

is a class-based routing version. It does not include subnet

information and therefore does not support variable length subnet masks

(VLSM). RIPv1 also lacks support for router authentication, making it

vulnerable to attacks.

RIPv2

carries a subnet mask and supports password

authentication security.

•

Transmit RIP versions:

Select the RIP protocol for transmitting network

data:

None

,

RIPv1

,

RIPv2 - Broadcast

, or

RIPv2

- Multicast

.

RIPv2 - Broadcast

(recommended) broadcasts data in the entire subnet.

RIPv2

- Multicast

sends data to multicast addresses. RIPv2 - Multicast also

helps to avoid unnecessary load by multicasting routing tables to adjacent

routers rather than broadcasting to the entire network.

Dynamic Routing for IPv6:

NOTE

The IPv6 tab is available if you enabled Dual-Stack IP on the

Setup > Network

page.

Check the box to enable

RIPng (RIP next generation)

, or uncheck the box to

disable it. (See the Glossary for more information.)

Configuring Static Routing

Enter the settings for

static routing

(see the Glossary for more information).

WARNING

Static routing is an advanced feature. Create these routes with care.

Add or edit entries as needed. Remember that the settings are not saved until you

click the Save button.

•

To add a new static route:

Enter the following settings, and then click

Add

to List

. You can enter up to 30 routes.

-

Destination IP:

Enter the network address of the remote LAN segment.

For a standard Class C IP domain, the network address is the first three

fields of the Destination LAN IP, while the last field should be 0.

-

Subnet Mask (IPv4 only):

Enter the subnet mask used on the

destination LAN IP domain. For Class C IP domains, the subnet mask is

255.255.255.0.

-

Prefix Length (Pv6 only):

Enter the prefix length.

-

Default Gateway:

Enter the IP address of the router of the network, for

which this static route is created. For example, if this network is

connected to the local router’s LAN port through another router, use the

WAN IP address of that router.

-

Hop Count:

Enter the appropriate value (maximum is 15). This indicates

the number of nodes that a data packet passes through before reaching

its destination. A node is any device on the network, such as a computer

or router.

-

Interface:

Select the interface to use for this route. Select a WAN

interface if this router provides Internet connectivity for your network.

Select

LAN

if this router gets Internet connectivity from a gateway router

on your LAN.
