Beacon Interval

A beacon is a packet broadcast by L13 to synchronize the wireless network.

The Beacon Interval value indicates how often the beacon is sent

DTIM Interval

The Delivery Traffic Indication Message (DTIM) is a countdown value that

informs wireless clients of the next opportunity to receive multicast and

broadcast messages. This value ranges between 1 and 16384.

Fragmentation

Threshold

Packets that are larger than this threshold are fragmented into multiple

packets. Try to increase the fragmentation threshold if you encounter high

packet error rates. Do not set the threshold too low, as this can result in

reduced networking performance.

RTS Threshold

L13 sends Request to Send (RTS) packets to the wireless client in order to

negotiate the dispatching of data. The wireless client responds with a Clear to

Send (CTS) packet, signaling that transmission can commence. If the number

of packets is less than the preset threshold, then the RTC/CTS mechanism will

not be active. If you encounter inconsistent data flow, try a minor reduction

of the RTS threshold size.

Shared Storage

You can connect an external storage to your L13 and share this storage with all the devices on your home network

(LAN and WLAN). The external storage can be connected via the USB port. Once the external storage is connected, it

appears on the home screen. The Shared Storage overview screen can be accessed via its link on the home page or via

In the management screen, you can see more information about the disk and also

check or format each of the disk partitions.

Shared Printer

With your L13, you can print documents and pictures from any computer in your local network. When connecting a

printer to the L13 USB port, it appears in the

Home



Overview

screen with a status “Connected”.

Note: When disconnecting the printer from L13, it remains

in the list with status “disconnected”.

Make sure that the printer is recognized on the computer connected to the LAN before printing (use the printer

network path for that), and that the printer’s driver is installed on the computer from

which you wish to send the

printing job.



To connect a printer:

1.

Connect the printer to the L13 USB port. It will automatically appear in the overview screen.

Figure 33: Shared Printer

2.

On every

computer connected to your LAN or WLAN, click on the “Start” button and type

“

\\

mbr” in the run

field.

3.

A Windows Explorer window will open and the printer will appear in it.

4.

Double click on the printer icon. An installation window will appear.

5.

If the driver is not found, you will be notified asked to point on the location of the driver. Once you install the

driver, you will have to repeat step number 4. For more information about installing a printer driver, refer to

the documentation of the operating system.

6.

Now the printer screen will be opened. This means the driver is installed properly and the computer is

connected to the printer. You can now use the printer to print from the computer.

To monitor all the printing jobs, go to

. Click on the printer name. The following

screen will appear. From here, you can monitor all the printer jobs online.

3.7.1

Firewall

The L13 gateway security suite includes security services: State-full Packet Inspection Firewall, user-authentication

protocols, and password protection mechanisms. These features together allow users to connect their computers to

the Internet and simultaneously be protected from the security threats of the Internet. The firewall, the cornerstone

of your gateway's security suite, has been tailored to the needs of the residential/office user and has been pre-

configured to secure your LAN.

Figure 36: L13 Firewall in Action

L13 secures the use of interactive applications, such as Internet gaming and video-conferencing.

Additional features, including Web site restrictions and access control, can also be configured locally by the user

through the L13 WBM or remotely by a service provider. The L13 firewall supports advanced filtering, which is

designed to allow control over the firewall's behavior. You can define specific input and output rules, control the order

of logically similar sets of rules and make a distinction between rules that apply to WAN and LAN network devices.

The Firewall service includes the following management screens:

An Overview screen allowing you to choose the security level for the firewall (refer to section

3.7.1.1).

An Access Control screen that can be used to restrict access from the home network to the Internet (refer to

section

3.7.1.2).

A Port Forwarding screen that can be used to enable access from the Internet to specified services provided by

computers in the home network and special Internet applications (refer to section

3.7.1.3).

A Gaming screen that can be used to earmark one computer on the local network for gaming (refer to section 3.7.1.4).

A DMZ Host screen that allows you to configure a LAN host to receive all traffic arriving at your gateway that does not

belong to a known session (refer to section

3.7.1.5).

A Port triggering screen that allows you to define port triggering entries and dynamically open the firewall for some

protocols or ports (refer to section

3.7.1.6).

A Website Restrictions screen that allows you to block LAN access to a certain host or Web site on the Internet (refer

to section

3.7.1.7).

The NAT screen allows you to manually control the translation of network addresses and ports (refer to

section

3.7.1.8).

The Connections screen allows you to view all the connections that are currently open (refer to section

3.7.1.9).

The Advanced Filtering screen allows you to implicitly control the firewall setting and rules (refer to section

3.7.1.10).

Overview

The firewall regulates the flow of data between the local network and the Internet. Both incoming and outgoing data

are inspected and then either accepted (allowed to pass through the L13) or rejected (barred from passing through
