WEP-Manual

You can provide a level of data security by enabling WEP (Wired Equivalent Privacy) for encryption of network

data. You can enable 40- or 128-bit WEP Encryption (depending on the capability of your client wireless card)

for IP traffic on your LAN.

WEP - Manual

allows you to enter your own encryption keys manually. This is a difficult process, but only

needs to be done once. Avoid the temptation to enter all the same characters.

Key Length

: The drop-down menu selects the length of each encryption key. The longer the key, the stronger

the encryption and the more difficult it is to break the encryption.

Key

: You must enter a key using hexadecimal digits. For 40/64-bit encryption, you need ten digits; 26 digits for

128-bit WEP. Hexadecimal characters are 0 – 9, and a – f.

Examples:

±

40 bits: 02468ACE02

±

128 bits: 0123456789ABCDEF0123456789

Any WEP-enabled client must have an identical key of the same length as the router, in order to successfully

receive and decrypt the traffic. Similarly, the client also has a default key that it uses to encrypt its

transmissions. In order for the router to receive the client’s data, it must likewise have the identical key of the

same length.

NOTE:

WEP is a less current and less secure authentication method than WPA-PSK. It may be required if your wire-

less clients do not support WPA.

MAC Filtering

When you click the

MAC Filtering

link the MAC Filtering page appears.

MAC filtering allows you to specify which client PCs are allowed to join the wireless LAN by unique hardware

(MAC) address.

±

To enable this feature, select

Blacklist

or

Whitelist

from the

MAC Filtering Type

menu.

Blacklist

means that

only MAC addresses you specify will be denied access;

Whitelist

means that only MAC addresses you specify

will be allowed access.

±

You add wireless clients that you want to whitelist or blacklist for your wireless LAN by selecting them from

the

MAC Address

drop-down list or by entering the MAC addresses in the

Manual Entry

field provided.

±

Click the

Add

button.

Your entries will be added to a list of clients that will be either authorized (whitelisted) or disallowed

(blacklisted) depending on your selection.

±

Save

button.

WiFi Scan

Your device automatically checks for the best channel to broadcast wireless services. However, in some cases it

may be useful to switch to a different channel (1 through 11, for North America) on which the network will

broadcast.

The scan covers a frequency range within the 2.4 Ghz or 5.0 Ghz band. Channel selection depends on

government regulated radio frequencies that vary from region to region. Channel selection can have a

significant impact on performance, depending on other wireless activity close to this device. You need not

select a channel at any of the computers on your wireless network. They will automatically scan available

channels seeking a wireless device broadcasting on the SSID for which they are configured.

This scan will disconnect any wireless client devices from the wireless network.

If you want to scan for a different channel on which the device will broadcast, click the

Continue

button.

Subnets & DHCP

When you click the

Subnets & DHCP

link, the Subnets & DHCP page appears.

The server configuration determines the functionality of your DHCP settings. This functionality enables the

NVG599 to assign your LAN computer(s) a “private” IP address and other parameters that allow network

communication. This feature simplifies network administration because the NVG599 maintains a list of IP

address assignments. Additional computers can be added to your LAN without the need to configure an IP

address. This is the default mode for your NVG599 device.

Private LAN Subnet

±

Device IPv4 Address:

The IP address of your device as seen from the LAN.

±

Subnet Mask:

Subnet mask of your LAN.

DHCP

±

DHCPv4 Start Address:

First IP address in the range being served to your LAN by the NVG599 DHCP server.

±

DHCPv4 End Address:

Last IP address in the range being served to your LAN by the NVG599 DHCP server.

±

DHCP Lease

: Specifies the default length for DHCP leases issued by the router. Enter lease time in

dd:hh:mm:ss

(days/hours/minutes/seconds) format.

Public Subnet

±

Public Subnet Enable

: If you select

On

from the drop-down menu, you can enable a second subnet to dis-

tribute public addresses to DHCP clients; this means that IP addresses assigned to LAN clients will be public

addresses.

±

Public IPv4 Address

: The IP address of your NVG599 device as seen from the WAN.

±

Public Subnet Mask

: Public subnet mask.

±

DHCPv4 Start Address

: First IP address in the range being served from a DHCP public pool.

±

DHCPv4 End Address

: Last IP address in the range being served from a DHCP public pool.

±

Primary DHCP Pool

: Choose the source of the DHCP pool IP address assignment by selecting either

Private

(local to your LAN) or

Public

(assigned remotely).

Cascaded Router

±

Cascaded Router Enable

: If you have another router behind this device, choose

On

from the drop-down

menu.

±

Cascaded Router Address

: If you chose

On

from the drop-down menu, enter the IP address of the router

you are using behind this device in the LAN private IP subnet range.

±

Network Address

: If you chose

On

from the drop-down menu, enter the Network Address that defines the

range of IP addresses available to clients of the router you are using behind this device.

±

Subnet Mask

: If you chose

On

from the drop-down menu, enter the subnet mask for the network address

that defines the range of IP addresses available to clients of the router you are using behind this device.

If you make any changes here, click the

Save

button, and if prompted, restart the NVG599 device.

Link:

IP Allocation

When you click the

IP Allocation

link, the IP Allocation page appears.

The IP Allocation page lets you set aside or assign IP addresses to client devices on your network. With IP

allocation, you can configure known devices to either use DHCP for dynamic IP address assignment, or set

aside a specific IP address for

a client device. When IP allocation is enabled for a client, that device is assigned

a pre-determined IP address by the DHCP server of the NVG599. IP allocation lets you set up client devices as

common DHCP systems, but ensures that they always receive the same IP address from the gateway.

The IP Allocation table shows a list of all identified and active client devices the NVG599 is serving.

To change the allocation method used by a client:

1.

Locate the client in the IP Allocation table. The client may be identified by the

Name

value (in the

IPv4

Address/Name

column) or the device MAC address.

2.

Click the

Allocate

button associated with the client entry.

NOTE:

IP Allocation functions require you to enter your

NVG599

Gateway’s access code. Information on the device

code is provided in

“Device Access Code” on page 24
