WLAN ADSL2+ Router

QoS Setting

Go to

Advanced Setup -> QoS

to setup QoS features. This option will provide better service

of selected network traffic over various technologies.

VLAN

Go to

Advanced Setup -> VLAN

to enable VLAN features. Virtual LAN (VLAN) is a group of

devices on one or more LANs that are configured so that they can communicate as if they

were attached to the same wire, when in fact they are located on a number of different LAN

segments. Because VLANs are based on logical instead of physical connections, it is very

flexible for user/host management, bandwidth allocation and resource optimization.

VLAN PVID

Go to

Advanced Setup -> VLAN-> Assign VLAN PVID for each interface

to setup VLAN

PVID features.

Each physical port has a default VID called PVID (Port VID). PVID is assigned

to untagged frames or priority tagged frames (frames with null (0) VID) received on this port.

VLAN Group

Go to

Advanced Setup -> VLAN-> Define VLAN Group

to setup VLAN group features.

Firewall

Go to

Advanced Setup ->Firewall

to setup Firewall features. Select this option can

automatically detect and block Denial of Service (DoS) attacks, such as Ping of Death, SYN

Flood, Port Scan and Land Attack.

9.0 Universal Plug-and-Play (UPnP)

9.1 Universal Plug and Play Overview

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP

for simple peer-to-peer network connectivity between devices. An UPnP device can

dynamically join a network, obtain an IP address, convey its capabilities and learn about other

devices on the network. In turn, a device can leave a network smoothly and automatically

when it is no longer in use.

9.2 How do I know if I'm using UPnP?

UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each

UPnP compatible device installed on your network will appear as a separate icon. Selecting

the icon of a UPnP device will allow you to access the information and properties of that

device.

9.3 NAT Traversal

UPnP NAT traversal automates the process of allowing an application to operate through NAT.

UPnP network devices can automatically configure network addressing, announce their

presence in the network to other UPnP devices and enable exchange of simple product and

service descriptions. NAT traversal allows the following:



Dynamic port mapping



Learning public IP addresses



Assigning lease times to mappings

Windows Messenger is an example of an application that supports NAT traversal and UPnP.

See the

Network Address Translation (NAT)

chapter for further information about NAT.

9.4 Cautions with UPnP

The automated nature of NAT traversal applications in establishing their own services may

present network security issues. Network information and configuration may also be obtained

and modified by users in some network environments.

All UPnP-enabled devices may communicate freely with each other without additional

configuration. Disable UPnP if this is not your intention.

UPnP broadcasts are only allowed on the LAN.

See later sections for examples of installing UPnP in Windows XP and Windows Me as well as

an example of using UPnP in Windows.

9.5 Configuring UPnP

From the Site Map in the main menu, click UPnP under Access Managemen to display the

screen shown next.

The following table describes the labels in this screen.

LABEL

DESCRIPTION

UPnP

Select this checkbox to activate UPnP. Be aware that anyone could use a

UPnP application to open the web configuration's login screen without

entering WLAN ADSL2+ Router's IP address (although you must still enter

the password to access the web configuration).

Auto configured

Select this check box to allow UPnP-enabled applications to automatically

configure WLAN ADSL2+ Router so that they can communicate through

WLAN ADSL2+ Router, for example by using NAT traversal, UPnP

applications automatically reserve a NAT forwarding port in order to

communicate with another UPnP enabled device; this eliminates the need

to manually configure port forwarding for the UPnP enabled application.
