More Info

Services

This section lists the services on the computer that are available to other computers,

either from the LAN, via Web access, or both. Services are accessible only when

enabled on the computer. When a service is accessible from the LAN, you can

activate it by clicking either its name or the URL that appears (see Figure 23). When a

service is accessible via Web access, you can activate it by clicking the Web Access

link that appears. Available services are:

Shared Files

- Access the computer's shared files directory.

HTTP

- Access the computer's HTTP server (if available).

FTP

- Open an FTP session with the computer.

Telnet

- Open a Telnet session with the computer.

Remote Desktop

- Remotely control a Windows based computer with the Remote Desktop

utility.

VNC

–

Indicates if Virtual Network Computing is supported by the host.

Add Access Control Rule

- Block access to Internet services from the computer, or allow

access if the firewall is set to a "High" security level (for more information, refer to

section

3.7.1.2.)

Add Port Forwarding Rule

- Expose services on the computer to external Internet users (for

more information, refer to section

3.7.1.3).

Connection

Information

This section displays various details regarding the computer's connection settings. To

view the connection's properties, click the network connection type (

Bridge

in the

above example). The relevant properties screen appears. In addition, you can run a

Ping or ARP test by clicking the respective

Test Connectivity

button. The tests are

performed in the

Diagnostics screen (refer to section

3.7.1.9).

Statistics

This section displays the computer's traffic statistics, such as the number and size of

transmitted and received packets.

Connection

List

This section displays the list of connections opened by the computer on the L13

firewall. The table displays the computer's source LAN IP address and port, the

gateway's IP address and port to which it is translated, and the destination WAN IP

address and port.

3.6.2

WiFi

The L13 system can be used as a WiFi router, connecting to wireless devices according to the IEEE 82.11b/g/n

standards. The WLAN interface can be enabled or disabled. The preferred WLAN data rate can be configured to be

either B-G-MIXEDMODE, B-G-N-MIXEDMODE, G-MODE-ONLY, B-MODE-ONLY or N-MODE-ONLY. The wireless access

to the L13 may be allowed or denied for specific wireless clients

’

MAC addresses.

Configure the fields as follows:

Parameter

More Info

Enable WiFi

Check or uncheck this box to enable or disable the WiFi connection

WiFi Network (SSID)

The L13 supports a single SSID. The system arrives with a default

preconfigured SSID that may be manually changed in this field.

Note: The SSID is case sensitive.

SSID Broadcast

By default, the SSID is broadcast so that all wireless client devices within

range of it can detect it. You can choose to hide the SSID. If you do so, only

client devices that know the SSID will be able to connect to L13, and the SSID

will have to be entered manually on each device in order for it to connect.

Clear this option to turn off broadcasting of the SSID.

802.11 Mode

Select the type of connection. Choose from B-G-MODE, G-MODE-ONLY, B-G-

N-MODE, G-N-MODE, N-MODE-ONLY

Channel

A specific wireless channel, over which the system will operate, can be

chosen. It may also be set up automatically.

Channel Width Mode

This option appears on platforms supporting 802.11n only. At this point

make sure you always work in "20 MHz only".

Network Authentication

Only the 'Open System Authentication' option is available in this version.

MAC Filtering Mode

To enable MAC address filtering, select either “Allow” or “Deny”.

If you select “Allow,” only devices whose MAC addresses appear in the

MAC

Filtering Table (defined in the next section) are allowed to connect to the

Wi-

Fi network. If you select “Deny,” devices whose MAC addresses appear in

the MAC Filtering Table are not allowed to connect to the Wi-Fi network (all

other devices are allowed to connect).

3.6.2.3

MAC Filtering Settings

The MAC Filtering Table contains a list of MAC addresses for filtering.

The filtering rule is defined above, under “MAC

Filtering Mode”.

Transmission Settings

The transmission settings appear in the bottom section of the Wi-Fi screen.

Figure 31: Transmission Properties Section

Configure the transmission properties as follows:

Parameter

More Info

Transmission Rate

The transmission rate is set according to the speed of your WiFi connection.

Select the transmission rate from the drop-down menu, or select 'Auto' to

have L13 automatically use the fastest possible data transmission rates (the

only option when using 802.11ng). Note that if your wireless connection is

weak or unstable, it is best to select a low transmission rate.

Transmit Power

The percentage of maximum transmission power.

CTS Protection Mode

CTS Protection Mode boosts your gateway's ability to intercept 802.11g and

802.11b transmissions. Conversely, CTS Protection Mode decreases

performance. Leave this feature disabled unless you encounter severe

communication difficulties between the gateway and 802.11g products. If

enabling, select "Always". Select "Auto" to have L13 decide automatically

whether or not to use this feature.

CTS Protection Type

Select the type of CTS protection

—

CTS-only or RTS-CTS.

Frame Burst

This feature (also known as

packet bursting

) increases the speed of a 802.11g-

based wireless network by unwrapping short packets and rebundling them

into a larger one.

Frame Burst

–

Max Number - At any given time, only one wireless client can

communicate with the access point. Therefore, clients, competing for air

time, transmit data in frame bursts. Use this field to determine the maximum

number of frames that L13 will allow clients to transmit in a single frame

burst.

Frame Burst

–

Burst Time - The maximum length of a frame burst. Limit the

time of a frame burst to avoid large frames from taking communication

precedence.
