Traffic Meter Parameters

Parameter

Description

Enable Traffic Meter

Check this if you wish to record the volume of Internet traffic passing

through the Router's WAN1 or WAN2 port.WAN1 or WAN2 can be selected

through the drop down menu, the entire configuration is specific to each

wan interface.

•

No Limit - If this is selected specified restriction will not be applied when

traffic limit is reached.

•

Download only - If this is selected the specified restriction will be applied

to the incoming traffic only

•

Both Directions - If this is selected the specified restriction will be applied

to both incoming and outgoing traffic only

Enable Monthly Limit

Use this if your ISP charges for additional traffic. If enabled, enter the

monthly volume limit and select the desired behavior when the limit is

reached.

Note

: Both incoming and outgoing traffic are included in the limit.

Increase this month's limit

Use this to temporarily increase the Traffic Limit if you have reached the

monthly limit, but need to continue accessing the Internet. Check the

checkbox and enter the desired increase. (The checkbox will automatically

be cleared when saved so the increase is only applied once.)

This month's limit

This displays the limit for the current month.

Restart traffic counter

This determines when the traffic counter restarts. Choose the desired time

and day of the month.

Restart Counter Now

Click this button to restart the Traffic Counter immediately.

Send E-mail Report before

restarting counter

If checked, an E-mail report will be sent immediately before restarting the

counter. You must configure the E-mail screen in order for this function to

work (see

“Event Logs and Alerts” on page 4-32

).

When limit is reached

Select the desired option:

•

Block all traffic - all access to and from the Internet will be blocked.

•

Block all traffic except E-mail - Only E-mail traffic will be allowed. All other

traffic will be blocked.

•

If using this option, you may also select the Send E-mail alert option. You

must configure the E-mail screen in order for this function to work.

Internet Traffic Statistics

This displays statistics on Internet Traffic via the WAN port. If you have not

enabled the Traffic Meter, these statistics are not available.

Traffic by Protocol

Click this button if you want to know more details of the Internet Traffic. The

volume of traffic for each protocol will be displayed in a sub-window.Traffic

counters are updated in MBytes scale, counter starts only when traffic

passed is at least 1MB.

Chapter 3

Wireless Configuration

This chapter describes how to configure the wireless features of your ProSafe DGFV338.

In planning your wireless network, you should consider the level of security required. You should

also select the physical placement of your DGFV338 in order to maximize the network speed (see

Chapter 2, “Basic Installation and Configuration”

). For further information on wireless

networking, refer to

Appendix B, “Related Documents

for a link to resource material on the

NETGEAR website.

Implementing Wireless Security

Be aware that the time it takes to establish a wireless connection can vary depending on both your

security settings and placement. WEP connections can take slightly longer to establish. Also, WEP

encryption can consume more battery power on a notebook computer.

Note:

Failure to follow these guidelines can result in significant performance degradation

or inability to wirelessly connect to the wireless firewall. For complete range and

performance specifications, please see

Appendix A, “Default Settings and

Technical Specifications

.”

Note:

Indoors, computers can connect to wireless networks at ranges of 300 feet or more.

Such distances allow others outside of your area to access your network.

Wireless Configuration

v1.0, April 2007

Unlike wired network data, your wireless data transmissions can extend beyond your walls and

can be received by anyone with a compatible adapter. For this reason, use the security features of

your wireless equipment. The wireless firewall provides highly effective security features which

are covered in detail in this chapter.

There are several ways you can enhance the security of your wireless network:

•

Restrict Access Based on MAC Address.

You can allow only trusted PCs to connect so that

unknown PCs cannot wirelessly connect to the DGFV338. Restricting access by MAC address

adds an obstacle against unwanted access to your network, but the data broadcast over the

wireless link is fully exposed.

•

Turn Off the Broadcast of the Wireless Network Name SSID.

If you disable broadcast of

the SSID, only devices that have the correct SSID can connect. This nullifies wireless network

“discovery” feature of some products, such as Windows XP, but the data is still exposed.

•

WEP.

Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared

Key authentication and WEP data encryption will block all but the most determined

eavesdropper.

•

WPA/WPA2 with RADIUS or WPA/WPA2-PSK.

Wi-Fi Protected Access (WPA and

WPA2) data encryption provides data security. The very strong authentication along with

dynamic per frame rekeying of WPA and WPA2 make it virtually impossible to compromise.

Because this is a new standard, wireless device driver and software availability may be

limited.

Understanding Wireless Settings

Before configuring your wireless settings, you may want to review the Wireless Settings choices to

determine what type of security is required for your wireless LAN network and to gather any

security information that may be required. A description of the various types of security available

on the wireless firewall, as well as a description of the other wireless settings you will be prompted

to make follows.

The Wireless Settings menu is divided into two basic sections: (1) Wireless Networks and Wireless

Access Point which deals with setting up the proper stations, channels, and regions for your

wireless device; as well as setting up the appropriate broadcast method, and (2) Wireless Security

Type which deals with setting up the security on each of your LANs.
