server or printer. You can connect a USB hard disk or a printer to the USB interface

of the Giga762SX WLAN dsl and make them available to all users in your network.

The Giga762SX WLAN dsl supports

DHCP

for dynamic IP configuration of the local

area network, and

DNS

for domain name mapping.

u

Connecting phones and Internet telephony

The Giga762SX WLAN dsl permits

–

Internet telephony via the DSL port.

–

Fixed network telephony via the analogue port.

–

Connection of two analogue phones for Internet telephony and for fixed network

calls as well as connection of wireless SIP phones and PCs with SIP clients for

Internet telephony.

–

Connection of an answering machine or fax.

Data transfer for

VoIP

is handled by the

SIP

protocol with high connection and voice

quality. If the Internet connection has been interrupted or you do not want to make

a call via VoIP, you can simply make a call via the fixed network (if a fixed network

phone is connected).

Security functions

The Giga762SX WLAN dsl offers comprehensive security measures:

–

Firewall

protection against unauthorised access from the Internet

All PCs in the local area network use the

Public IP address

of the Giga762SX WLAN

dsl for their Internet connections, which makes them 'invisible' on the Internet.

The Giga762SX WLAN dsl only allows access from the Internet if this has been

requested from within the local area network.

With the firewall, the Giga762SX WLAN dsl also offers comprehensive protection

against hacker attacks.

–

Service filtering

The Giga762SX WLAN dsl can filter Internet access. Here you determine which

PCs may access which Internet services.

–

Access control and encryption for the local area network

The Giga762SX WLAN dsl is delivered with a predefined individual encryption

(WPA2-PSK/WPA-PSK with pre-shared key). You will find the corresponding infor-

mation at the label on the devices bottom. So, your wirless network is protected

against unauthorised access.

If there are wireless network adapters of your PCs which do not support this

encryption method, you can use other encryption methods and authentication

methods (WEP, WPA/WPA2, 802.1x) to prevent unauthorised access to your wire-

less LAN or to make data illegible to unauthorised parties.

With MAC access control you can allow wireless access to selected PCs.

Offering your own services on the Internet

–

If you want to offer your own services on the Internet, you can set up the

Giga762SX WLAN dsl as a virtual server without permitting further access to the

local area network.

–

DMZ

(Exposed Host)

This allows you to release a PC in your local area network for unlimited access

from the Internet. Note that in this case your local area network will no longer be

adequately protected against Internet attacks.

u

Providing an HTTP or FTP server via USB interface

–

You can easily establish an FTP or an HTTP server for Internet access with the

Giga762SX WLAN dsl.

–

You can connect a USB hub to the USB port on your Giga762SX WLAN dsl and

thereby at the same time provide a printer and a storage medium for all clients in

your local area network.

Overview of the installation steps

1.

First install an Ethernet network card or a wireless

Network adapter

in the PCs you

want to connect to the Giga762SX WLAN dsl. The installation is described in the user

guides for these products.

2.

Then make the necessary connections (PCs, phones, splitter) on the Giga762SX

WLAN dsl and activate the device (page 25).

3.

Before the PCs can communicate with the Giga762SX WLAN dsl and with each other

in a local network, you may have to change your network settings (page 35). Con-

figure these network settings on

one

PC first so that it can establish a connection to

the Giga762SX WLAN dsl. You can then use this PC to configure the device. To find

out how to do this, refer to the section entitled "Configuring the local area network"

on the CD-ROM.

4.

With a wireless connection, you establish the link from the PC's wireless network

adapter to the Giga762SX WLAN dsl. This is described in the user guide for the net-

work adapter. If the wireless network adapter provides WPS, you can establish the

connection with a simple click (see page 33).

5.

Then configure the Giga762SX WLAN dsl to activate the device's Internet access (re-

fer to the section entitled "Basic Setup Wizard" on page 42"). To

do this you will need the access data for your Internet service pro-

vider.

6.

If you want to connect more PCs to the Giga762SX WLAN dsl,

configure their network settings and set up the local area net-

work accordingly (refer to the section entitled "Configuring the

local area network" on the CD-ROM).

For experienced users

The default settings for the Giga762SX WLAN dsl are:

–

IP address: 10.0.0.2

–

Subnet mask: 255.255.255.0

–

SSID: individually preset, see the label on the devices bottom

Caution:

The Giga762SX WLAN dsl is delivered with a preset individual encryption

(WPA2-PSK/ WPA-PSK with pre-shared key). You will find the key at the label on the

devices bottom.

Please remember:

When installing wireless network adapters, use the preset

SSID

and key which are

shown at the label on the devices bottom.
