WAN Setting (Internet connection)

The router is pre-configured with default settings that are sufficient for many

networks. However, special settings may be required by your ISP (Internet Service

Provider) or broadband (DSL or cable) carrier. Refer to the setup information

provided by your ISP.

NOTE

You also can set up your Internet connection by using the Basic Setup Wizard. In the

navigation tree, click

Wizard

. In the

Basic Setup

section, click

Launch Now

.

The

WAN Setting

table displays the existing settings for each interface, such as

DMZ, WAN1, or WAN2. The listed interfaces depend on the router model and the

settings that you enter for ports such as DMZ/Internet (all models) and the Dual-

Function ports (Cisco RV016).

Perform the following actions, as needed.

•

To configure the WAN with IPv6 addressing:

Click the

IPv6

tab. Then

proceed with the other tasks listed below.

Note: 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.

•

To change the number of WAN ports (Cisco RV016 only):

Use the drop-

down list to choose the number of WAN ports that you want to enable. The

default selection is 2. If you configure additional WAN ports, the Dual-

Function Ports are used for this purpose.

DMZ Setting

On Cisco RV042, RV042G, and RV082, you can configure the Internet/DMZ port

for use as a DMZ (De-Militarized Zone or De-Marcation Zone). Cisco RV016 has a

dedicated DMZ port. A DMZ allows Internet traffic to access specified hosts on

your network, such as FTP servers and web servers. The rest of your network

resources are kept private.

This feature requires that you have a publicly routable IP address for each host on

the DMZ. You can contact your ISP about getting an additional IP address for this

purpose.

NOTE

•

Using the DMZ is preferred and is, if practical, a strongly recommended

alternative to using public LAN servers or putting these servers on WAN

ports where they are not protected and not accessible by users on the LAN.

•

Each of the servers on the DMZ will need a unique, public Internet IP

address. Your ISP should be able to provide these addresses, as well as

information on setting up public Internet servers. If you plan to use the DMZ

setting, contact your ISP for the static IP information. If your ISP provides

only one static or several dynamic IP addresses, consider using the DMZ

host feature. See

Setting Up a DMZ Host, page 43

.

Perform the following actions, as needed.

•

To configure the DMZ with IPv6 addressing:

Click the

IPv6

tab. Then

proceed with the other tasks in this section.

Note: 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.

•

To enable DMZ on the DMZ/Internet port (Cisco RV042, RV042G, and

RV082 only):

Check the

Enable DMZ

box to enable this feature. Then edit

the DMZ settings, as described below. If you want to use the port as a WAN

port instead, uncheck the box, and be sure to configure the WAN settings on

the

Dual WAN

page. (See

Setting Up Dual WAN and Multi-WAN

Connections, page 73

.)

Choose a connection type, as described below.

-

Obtain an IP Automatically:

Choose this option if your ISP dynamically

assigns an IP address. For example, most cable modem subscribers use

this connection type. Your ISP will assign the settings, including the DNS

server IP address. If you want to specify a DNS server, check the

the Following DNS Server Addresses

box. Then enter an IP address in

the

DNS Server (Required) 1

box. Optionally, you can enter a second

DNS server. The first available DNS entry is used.

-

Static IP:

Choose this option if your ISP assigned a permanent IP

address to your account. Then enter the settings provided by your ISP:

Specify WAN IP Address:

The external IP address that your ISP

assigned to your account.

Subnet Mask (IPv4):

The subnet mask specified by your ISP.

Prefix Length (IPv6):

The prefix length specified by your ISP.

Default Gateway Address:

The IP address of the default gateway.

DNS Server (Required) 1:

The IP address of the specified DNS server.

Optionally, enter a second DNS server. The first available DNS entry is

used.

-

PPPoE (Point-to-Point Protocol over Ethernet):

Choose this option if

your ISP uses PPPoE (Point-to-Point Protocol over Ethernet) to establish

Internet connections (typical for DSL lines). Then enter the settings

provided by your ISP:

Username

and

Password:

Enter the username and password for your

ISP account. The maximum number of characters is 60.

Connect on Demand:

This feature may be helpful if you are billed based

on the time that you are connected to the Internet. When this feature is

enabled, the connection will be disconnected after a specified period of

inactivity (Max Idle Time). As soon as you attempt to access the Internet

again, the router automatically re-establishes your connection. If you

enable this feature, also enter the

Max Idle Time

, which is number of

minutes that the connection can be inactive; when this limit is reached,

the connection is terminated. The default Max Idle Time is 5 minutes.

Keep Alive:

This feature ensures that your router is always connected to

the Internet. When this feature is enabled, the router keeps the

connection alive by sending out a few data packets periodically. This

option keeps your connection active indefinitely, even when it sits idle. If

you enable this feature, also enter the

Redial Period

to specify how

often the router verifies your Internet connection. The default period is

30 seconds.
