environment. This function boosts the Cisco RV120W’s ability to catch all wireless

transmissions but severely decreases performance.

STEP

8

The Short Retry Limit and Long Retry Limit fields determine the number of times

the Cisco RV120W will reattempt a frame transmission that fails. The limit applies

to both long and short frames of a size less than or equal to the RTS threshold.

STEP

Click Save.

Configuring Wi-Fi Protected Setup

You can configure Wi-Fi Protected Setup (WPS) on the Cisco RV120W to allow

WPS-enabled devices to more easily connect to the wireless network.

STEP 1

Choose Wireless > WPS.

STEP

2

In the VAP field, select the wireless network on which you want to enable WPS.

The network must use WPA, WPA2, or WPA+WPA2 security.

NOTE

You can enable WPS on only one of the four networks, or virtual access points.

STEP

3

Under WPS Status, choose Enable to allow WPS configuration. By default, WPS is

disabled.

STEP

4

Click Save.

To set up a WPS-enabled device in the network:

STEP 1

Choose Wireless > WPS.

STEP

2

Choose the WPS setup method:

•

Setup Using a PIN—In the WPS Setup Method section, in the Station PIN

field, enter the personal identification number (PIN) of the device you want

to connect to the network. You must log in to that device to obtain its WPS

PIN. Then click Configure via PIN. After clicking this button on the Cisco

RV120W, on the WPS-enabled device, select the necessary option to begin

WPS. The device should begin communication with the Cisco RV120W.

•

Setup Using a WPS Button—If the device you want to connect has a WPS

button, push the button on the device. Then, on the Cisco RV120W, click

Configure via PBC (push button configuration).

Configuring a Wireless Distribution System (WDS)

A Wireless Distribution System (WDS) is a system that enables the wireless

interconnection of access points in a network. It allows a wireless network to be

expanded using multiple access points without the need for a wired backbone to

link them.

WDS peers are other access points in the network connected in the WDS. All

base stations in a WDS must be configured to use the same radio channel, method

of encryption (none, WEP, or WPA) and encryption keys.

To configure a WDS:

STEP 1

Choose Wireless > WDS.

STEP

2

Check the Enable box to enable WDS in the Cisco RV120W.

STEP

3

Enter a WPA Key (password) for authentication.

STEP

4

Click Save.

You can manually add WDS peers that can connect to the Cisco RV120W:

STEP 1

In the WDS Peer Table, click Add.

STEP

2

Enter the MAC (hardware) address of the WDS peer and click Save.

Cisco RV120W Firewall Features

You can secure your network by creating and applying access rules that the

Cisco RV120W uses to selectively block and allow inbound and outbound Internet

traffic. You then specify how and to what devices the rules apply. You can

configure the following:

•

Services or traffic types (examples: web browsing, VoIP, other standard

services and also custom services that you define) that the router should

allow or block.

•

Rules for outbound (from your LAN to the Internet) or inbound (from the

Internet to your LAN) traffic.

•

Schedules as to when the router should apply rules.

•

Keywords (in a domain name or on a URL of a web page) that the router

should allow or block.

•

MAC addresses of devices whose inbound access to your network the

router should block.

•

Port triggers that signal the router to allow or block access to specified

services as defined by port number.

•

Reports and alerts that you want the router to send to you.

You can, for example, establish restricted-access policies based on time-of-day,

web addresses, and web address keywords. You can block Internet access by

applications and services on the LAN, such as chat rooms or games. You can block

just certain groups of PCs on your network from being accessed by the WAN or

public network.

Inbound (Internet to LAN) rules restrict access to traffic entering your network,

selectively allowing only specific outside users to access specific local resources.

By default, all access from the insecure WAN side is blocked from accessing the

secure LAN, except in response to requests from the LAN or DMZ. To allow

outside devices to access services on the secure LAN, you must create a firewall

rule for each service.

If you want to allow incoming traffic, you must make the router's WAN port IP

address known to the public. This is called “exposing your host.” How you make

your address known depends on how the WAN ports are configured; for the

Cisco RV120W, you may use the IP address if a static address is assigned to the

WAN port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name can

be used.

Outbound (LAN to Internet) rules restrict access to traffic leaving your network,

selectively allowing only specific local users to access specific outside resources.

The default outbound rule is to allow access from the secure zone (LAN) to the

insecure WAN. To block hosts on the secure LAN from accessing services on the

outside (insecure WAN), you must create a firewall rule for each service.
