Host Name and Domain Name

Some ISPs require that you assign a host name and domain name to identify your

router on the ISP network. Default values are provided, but you can change them if

needed.

•

Host Name:

Keep the default setting or enter a host name specified by your

ISP.

•

Domain Name:

Keep the default setting or enter a domain name specified

by your ISP.

IP Mode

Choose the type of addressing to use on your network:

•

IPv4 Only—

Use only IPv4 addressing.

•

Dual-Stack IP—

Use IPv4 and IPv6 addressing. After you enable this option

by saving the settings on this page, you can configure both IPv4 and IPv6

addresses for LAN, WAN, and DMZ settings on this page.

LAN Setting (device IP address and subnets)

The default LAN settings should be sufficient for most small businesses, but if

needed, you can change the LAN IP address of the router and enable multiple

subnets.

•

Changing the device IP address, page 28

•

Enabling multiple subnets (IPv4 only), page 29

NOTE

If you enabled Dual-Stack IP for the IP Mode, you can click the IPv6 tab to configure

IPv6 addresses.

Changing the device IP address

STEP 1

Enter the following information:

•

For IPv4:

Click the

IPv4

tab, and then enter the

Device IP Address

and

Subnet Mask

. The default IP address is 192.168.1.1, and the default subnet

mask is 255.255.255.0.

Note: The MAC address of the router also appears in this section. This value

cannot be changed.

•

For IPv6:

Click the

IPv6

tab, and then enter the

IPv6 Address

and the

Prefix

Length

. The default IP address is fc00::1, and the default prefix length is 7.

The IPv6 tab is available only if

Dual-Stack IP

is enabled in the

IP Mode

section. If you change the IP Mode setting, you must save the settings before

you continue.

Note:

To configure global IPv6 prefixes for your LAN devices, go to the

WAN

Settings

section, click the

IPv6

tab, and click the

Edit

icon for the WAN

interface. Then enter the LAN IPv6 Address. For more information, see

WAN

Setting (Internet connection), page 31

STEP

Click

Save

to save your changes, or click

Cancel

to undo them.

After you click Save, a pop-up window displays a reminder that you will need to

use the new device IP address to launch the configuration utility. Click

to close

the message and continue with the IP address change, or click

Cancel

to close the

message without applying the changes.

STEP

Release and renew the IP address of your PC. You should then receive a new IP

address in the new DHCP range for the router.

Notes:

•

To release and renew your address in Windows:

From the Start menu, open

the

Network Connections

window. Right-click on the connection and

choose

Disable

. Right-click again and enable the connection. To verify, right-

click and choose

Status

. Then click the

Support

tab to view the assigned IP

address.

•

By default, the router is a DHCP server that assigns IP addresses

dynamically to all connected devices. For example, if you choose

192.168.15.1 as the device IP address, devices will receive IP addresses in

the range of 192.168.2.x.

•

By default, a Windows PC receives an IP address dynamically.

•

If you previously disabled the router’s DHCP server or set a static IP address

on the PC, you will need to configure a new static IP address in the new

range.

STEP

To reconnect to the configuration utility, enter the new device IP address in the

address bar of your browser.

Enabling multiple subnets (IPv4 only)

Typically, a Cisco RV0xx Series router is used as an access router, with a single

LAN subnet. By default, the firewall is pre-configured to deny LAN access if the

source IP address is on a different subnet than the router’s LAN IP address.

However, you can enable multiple subnets to allow this router to work as an edge

device that provides Internet connectivity to different subnets in your LAN.

STEP 1

On the IPv4 tab, check the

Enable Multiple Subnet

box to enable this feature.

Uncheck the box to disable this feature.

STEP

Click

Add/Edit

to create or modify the subnets. After you click the button, the

Multiple Subnet Management

window appears.

STEP

In the pop-up window, add or edit entries as needed.

•

To add a new subnet:

Enter a LAN IP Address and a Subnet Mask. Click

Add

to list

. The IP address and subnet mask appear in the list. Repeat this step

as needed to add other subnets.

Examples:

Two subnets: If the router has a LAN IP address of 192.168.1.1 with a

subnet mask of 255.255.255.0, you could set up a second subnet with a

LAN IP address of 192.168.2.1 and a subnet mask of 255.255.255.0.

Four subnets: If the router has a LAN IP Address of 192.168.1.1 and the

Subnet Mask of 255.255.255.192, you could create three subnets with IP

addresses of 192.168.2.65, 192.168.2.129, and 192.168.2.193, with the

same subnet mask of 255.255.255.192.

•

To add another subnet:

Enter the information, and then click

Add to list

•

To modify a subnet:

Click the subnet in the list. The existing values appear

in the text fields. Enter the new information, and then click

Update

. If you do

not want to modify the selected subnet, you can click

Add New

to clear the

text fields.

•

To delete a subnet:

Click the subnet in the list, and then click

Delete
