Wireless ADSL2/2+ Modem Router Features

The Wireless ADSL2/2+ Modem Router incorporates many advanced features, care­fully designed to provide sophisticated functions while being easy to use.

Internet Access Features

Shared Internet Access. All users on the LAN or WLAN can access the
Internet through the Wireless ADSL2/2+ Modem Router, using only a single ex­ternal IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation).
Built-in ADSL2/2+ Modem. The Wireless ADSL2/2+ Modem Router has a
built-in ADSL2/2+ modem, supporting all common ADSL connections.
IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless
ADSL2/2+ Modem Router supports all common connection methods.
Auto-detection of Internet Connection Method. In most situations, the
Wireless ADSL2/2+ Modem Router can test your ADSL and Internet connection to determine the connection method used by your ISP.

Page 5
Introduction
Fixed or Dynamic IP Address. On the Internet (ADSL port) connection, the
Wireless ADSL2/2+ Modem Router supports both Dynamic IP Address (IP Ad­dress is allocated on connection) and Fixed IP Address.

Advanced Internet Functions

Application Level Gateways (ALGs). Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally.
Special Applications. This feature, also called Port Triggering, allows you to
use Internet applications which normally do not function when used behind a fire­wall.
Virtual Servers. This feature allows Internet users to access Internet servers
on your LAN. The required setup is quick and easy.
Dynamic DNS Support. DDNS, when used with the Virtual Servers feature,
allows users to connect to Servers on your LAN using a Domain Name, even if you have a dynamic IP address which changes every time you connect.
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN
users.
Firewall. As well as the built-in firewall to protect your LAN, you can define
Firewall Rules to determine which incoming and outgoing traffic should be permit­ted.
Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate
only at certain times. This provides great flexibility in controlling Internet -bound traffic.
Logs. Define what data is recorded in the Logs, and optionally send log data to a
Syslog Server. Log data can also be E-mailed to you.
VPN Pass through Support. PCs with VPN (Virtual Private Networking)
software using PPTP, L2TP and IPSec are transparently supported - no configura­tion is required.

VPN Features

IPSec Support. IPSec is the most common protocol.
Easy Configuration. The configuration required to allow 2 Wireless ADSL2/2+
Modem Routers to establish a VPN connection between them is easy accom­plished.

Wireless Features

Standards Compliant. The Wireless ADSL2/2+ Modem Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs.
Supports both 802.11b and 802.11g Wireless Stations. The 802.11g
standard provides for backward compatibility with the 802.11b standard, so both
802.11b and 802.11g Wireless stations can be used simultaneously.
Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are
supported.
WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key
sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before trans­mission, providing protection against snoopers.
5
Page 6
WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmis-
sion, providing protection against snoopers. The WPA-PSK is a later standard than WEP, and provides both easier configuration and greater security than WEP.
Wireless MAC Access Control. The Wireless Access Control feature can
check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN.
Simple Configuration. If the default settings are unsuitable, they can be
changed quickly and easily.

LAN Features

4-Port Switching Hub. The Wireless ADSL2/2+ Modem Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN.
DHCP Server Support. Dynamic Host Configuration Protocol provides a
dynamic IP address to PCs and other devices upon request. The Wireless ADSL2/2+ Modem Router can act as a DHCP Server for devices on your local LAN and WLAN.

Configuration & Management

Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration.
Configuration File Upload/Download. Save (download) the configuration
data from the Wireless ADSL2/2+ Modem Router to your PC, and restore (upload) a previously-saved configuration file to the Wireless ADSL2/2+ Modem Router.
Remote Management. The Wireless ADSL2/2+ Modem Router can be man-
aged from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet.
Network Diagnostics. You can use the Wireless ADSL2/2+ Modem Router to
perform a Ping or DNS lookup.

Security Features

Password - protected Configuration. Password protection is provided to prevent unauthorized users from modifying the configuration data and settings.
Wireless LAN Security. WPA-PSK, WEP and Wireless access control by
MAC address are all supported. The MAC-level access control feature can be used to prevent unknown wireless stations from accessing your LAN.
NAT Protection. An intrinsic side effect of NAT (Network Address Translation)
technology is that by allowing all LAN users to share a single IP address, the loca­tion and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the Wireless ADSL2/2+ Modem Router.
Firewall. All incoming data packets are monitored and all incoming server re-
quests are filtered, thus protecting your network from malicious attacks from external sources.
Protection against DoS attacks. DoS (Denial of Service) attacks can flood
your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavail­able. The Wireless ADSL2/2+ Modem Router incorporates protection against DoS attacks.

Page 22

DHCP

What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request.
The client request is made when the client device starts up (boots).
The DHCP Server provides the Gateway and DNS addresses to the client, as well
as allocating an IP Address.
The Wireless ADSL2/2+ Modem Router can act as a DHCP server.
Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP
client. This is the default Windows setting for the TCP/IP network protocol. How­ever, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client".
You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.)
Using the Wireless ADSL2/2+ Modem Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can:
Enable or Disable the Wireless ADSL2/2+ Modem Router's DHCP Server function.
Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless ADSL2/2+ Modem Router's, the following procedure is required.
Disable the DHCP Server feature in the Wireless ADSL2/2+ Modem Router. This setting is on the LAN screen.
Configure the DHCP Server to provide the Wireless ADSL2/2+ Modem Router's IP Address as the Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.

After changing the mode, this device will restart, which will take a few seconds. The menu will also be changed, depending on the mode you are in.
The Wireless Access Point can function in either Router or Modem mode. But generally it is not a good idea to combine a Modem with an Access Point, be­cause all data received from the wireless stations will be sent over the modem connection. (Since the modem is transparent, it does not examine the traffic to de­termine whether the traffic is for the LAN or the WAN.)

Overview

For each PC, the following may need to be configured:
TCP/IP network settings
Internet Access configuration
Wireless configuration

Windows Clients

This section describes how to configure Windows clients for Internet access via the Wireless ADSL2/2+ Modem Router.
The first step is to check the PC's TCP/IP settings. The Wireless ADSL2/2+ Modem Router uses the TCP/IP network protocol for all
functions, so it is essential that the TCP/IP protocol be installed and configured on each PC.

TCP/IP Settings - Overview

If using the default Wireless ADSL2/2+ Modem Router settings, and the default Windows TCP/IP settings, no changes need to be made.
By default, the Wireless ADSL2/2+ Modem Router will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots.
For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client.
If using a Fixed (specified) IP address, the following changes are re­quired:
The Gateway must be set to the IP address of the Wireless ADSL2/2+ Modem Router
The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re­configure the Router itself. Refer to Chapter 8 - Ad- vanced Setup for details.

Internet

This screen provides access to the DMZ, Special Applications and URL Filter features.
Page 60
Figure 45: Internet Screen
DMZ
This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all users on the Internet.
This allows almost any application to be used on the "DMZ PC".
The "DMZ PC" will receive all "Unknown" connections and data.
If the DMZ feature is enabled, you must select the PC to be used as the "DMZ
PC".
The "DMZ PC" is effectively outside the Firewall, mak­ing it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required.

Special Applications

If you use Internet applications which use non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the Wireless Router's firewall. In this case, you can define the application as a "Special Application".
The Special Applications screen can be reached by clicking the Special Applications button on the Internet screen.
You can then define your Special Applications. You will need detailed information about the application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the client (PC) viewpoint

Finish - Enter the end of the range of port numbers used by the application server, for data you send to it. If the application uses a single port number, enter it in both the "Start" and "Finish" fields.
Type - Select the protocol (TCP or UDP) used when you receive data from the special application or service. (Note: Some applica­tions use different protocols for outgoing and incoming data).
Start - Enter the beginning of the range of port numbers used by the application server, for data you receive. If the application uses a single port number, enter it in both the "Start" and "Finish" fields.
Finish - Enter the end of the range of port numbers used by the application server, for data you receive.

Using a Special Application
Configure the Special Applications screen as required.
On your PC, use the application normally. Remember that only one (1) PC can
use each Special application at any time. Also, when 1 PC is finished using a par­ticular Special Application, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 min­utes.

URL Filter

If you want to limit access to certain sites on the Internet, you can use this feature. The URL filter will check each Web site access. If the address, or part of the address, is included in the block site list, access will be denied.
On the Advanced Internet screen, select the desired setting:
Disable - disable this feature.
Block Always - allow blocking all of the time, independent of the Schedule page.
Block By Schedule - block according to the settings on the Schedule page.
Click the Configure URL Filter button to open the URL Filter screen, allowing you to create or modify the filter strings which determine which sites will be blocked.
The URL Filter screen is displayed when the Configure URL Filter button on the Advanced Internet screen is clicked.

Dynamic DNS (Domain Name Server)

This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you.
DDNS Services work as follows:
1. You must register for the service at one of the listed DDNS Service providers.
2. After registration, use the Service provider's normal procedure to obtain your desired Domain name.
3. Enter your DDNS data on the Wireless ADSL2/2+ Modem Router's DDNS screen, and enable the DDNS feature.
4. The Wireless ADSL2/2+ Modem Router will then automatically ensure that your current IP Address is recorded at the DDNS service provider's Domain Name Server.
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen.

Dynamic DNS Screen

Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following:

Firewall Rules

The Firewall Rules screen allows you to define "Firewall Rules" which can allow or prevent certain traffic. "Traffic" means incoming connection attempts, not packets.
By default:
All Outgoing traffic is permitted.
All Incoming traffic is denied.
Because of this default behavior, any Outgoing rules will generally Block traffic, and Incoming rules will generally Allow traffic.

Virtual Servers

This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to ac­cess a server on your LAN because:
Your Server does not have a valid external IP Address.
Attempts to connect to devices on your LAN are blocked by the firewall in this
device.
The "Virtual Server" feature solves these problems and allows Internet users to con­nect to your servers, as illustrated below.
Figure 56: Virtual Servers

IP Address seen by Internet Users

Note that, in this illustration, both Internet users are connecting to the same IP Ad­dress, but using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address.

Virtual Servers Screen

The "Virtual Servers" feature allows Internet Users to access PCs on your LAN.
The PCs must be running the appropriate Server Software.
For Internet Users, ALL of your Servers have the same IP address. This IP ad-
dress is allocated by your ISP.
To make it easier for Internet users to connect to your Servers, you can use the "DDNS" feature. This allows Internet users to connect to your Servers with a URL, rather than an IP address. This technology works even if your ISP allocates dy-

namic IP addresses (IP address is allocated upon connection, so it may change each time you connect).

PC (Server)
This lists a number of common Server types. If the desired Server type is not listed, you can create a Firewall Rule to achieve the same effect as the Virtual Server function.
Use this to Enable or Disable support for this Server, as required.
If Enabled, you must select the PC to which this traffic will be sent.
Select the PC for this Server. The PC must be running the appropriate Server software.
For each entry, the PC must be running the appropri­ate Server software.
If the desired Server type is not listed, you can define your own Servers, using the Firewall Rules.

Connecting to the Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g.
http://203.70.212.52 ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Servers using a URL, rather than an IP Address.

VPN Setup

The VPN (Virtual Private Network) feature in the Wireless ADSL2/2+ Modem Router allows you to create a VPN connection between 2 Wireless ADSL2/2+ Modem Routers, or a remote PC to establish a VPN connection to the Wireless ADSL2/2+ Modem Router.
To establish a VPN connection from a remote PC to the Wireless ADSL2/2+ Modem Router, you need suitable (IPSec) VPN client software on your PC.
For more information about VPNs, please refer to Appendix C - About VPNs.

VPN Policies

A "VPN Policy" contains all the configuration data for a particular VPN connection. Generally, you will have to create one policy for each site you wish to connect to. The remote VPN Gateway (or client) needs to have matching configuration.
Traffic covered by an enabled policy will automatically be sent via a VPN tunnel. If the VPN tunnel does not exist, it will be created.
The VPN tunnel is created according to the parameters in the SA (Security Asso- ciation).
The remote VPN Endpoint must have a matching SA, or it will refuse the connec- tion.
There are 2 types of VPN Policies:
Manual - All settings (including the keys) for the VPN tunnel are manually input at each end (both VPN Endpoints).
Auto - Some parameters for the VPN tunnel are generated automatically. This requires using the IKE (Internet Key Exchange) protocol to perform negotiations between the 2 VPN Endpoints.

VPN Auto Policy Screen

This screen is displayed when you click the Add Auto Policy button on the VPN Poli­cies screen, or when you edit an existing Auto Policy. It allows you to define or edit an
"Auto" VPN policy. An "Auto" VPN policy uses the IKE (Internet Key Protocol) to exchange and negotiate
parameters for the IPsec SA (Security Association). Because of this negotiation, it is not necessary for all settings on this VPN Gateway to match the settings on the re­mote VPN endpoint. Where settings must match, this is indicated.

Authentication Algorithm used for both IKE and IPSec. This setting must match the setting used on the remote VPN Gateway.
The key must be entered both here and on the remote VPN Gateway. This method does not require using a CA (Certifi­cate Authority).
This determines the time interval before the SA (Security Association) expires. (It will automatically be re-established if necessary.) While using a short time period (or data amount) increases security, it also degrades performance. It is com­mon to use periods over an hour (3600 seconds) for the SA Life Time. This setting applies to both IKE and IPSec SAs.
If enabled, security is enhanced by ensuring that the key is changed at regular intervals. Also, even if one key is broken, subsequent keys are no easier to break. (Each key has no relationship to the previous key.)
This setting applies to both IKE and IPSec SAs. When con­figuring the remote endpoint to match this setting, you may have to specify the "Key Group" used. For this device, the "Key Group" is the same as the "DH Group" setting in the IKE section.

Overview

Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users.
The available settings and features are:
PC Database
Config File
Logs & Email
This is the list of PCs shown when you select the "DMZ PC" or a "Virtual Server". This database is maintained automati­cally, but you can add and delete entries for PCs which use a Fixed (Static) IP Address.
Backup or restore the configuration file for the Wireless ADSL2/2+ Modem Router. This file contains all the configu­ration data.
View or clear all logs, set E-Mailing of log files and alerts.
Diagnostics Qos Remote Admin Routing Upgrade Firmware
Perform a Ping or DNS Lookup.
Allow settings to be changed from the Internet. Only required if your LAN has other Routers or Gateways. Upgrade the Firmware (software) installed in your Wireless
ADSL2/2+ Modem Router.

PC Database

The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC).
It eliminates the need to enter IP addresses.
Also, you do not need to use fixed IP addresses on your LAN.
However, if you do use a fixed IP address on some devices on your LAN, you should enter details of each such device into the PC database, using the PC Database screen.

PC Database Screen

An example PC Database screen is shown below.
Figure 62: PC Database
PCs which are "DHCP Clients" are automatically added to the database, and updated as required.
By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called "Obtain an IP Address automatically".
The Wireless ADSL2/2+ Modem Router uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter.
This system means you do NOT need to use Fixed (static) IP addresses on your LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC da­tabase if required.

This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the
LAN. If adding a new PC to the list, enter its name here. It is best if
this matches the PC's "hostname". Enter the IP Address of the PC. The PC will be sent a "ping" to
determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it.
This will add the new PC to the list. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it.

IP Address
MAC Address
Select the appropriate option:
Automatic - The PC is set to be a DHCP client (Windows: "Obtain an IP address automatically"). The Wireless ADSL2/2+ Modem Router will allocate an IP address to this PC when requested to do so. The IP address could change, but normally won't.
DCHP Client - Reserved IP Address - Select this if the PC is set to be a DCHP client, and you wish to guarantee that the Wireless ADSL2/2+ Modem Router will always allocate the same IP Address to this PC. Enter the required IP address.
Fixed IP Address - Select this if the PC is using a Fixed (Static) IP address. Enter the IP address allocated to the PC. (The PC itself must be configured to use this IP ad­dress.)
Select the appropriate option
Automatic discovery - Select this to have the Wireless ADSL2/2+ Modem Router contact the PC and find its MAC address. This is only possible if the PC is connected to the LAN and powered On.
MAC address is - Enter the MAC address on the PC. The MAC address is also called the "Hardware Address", "Physi­cal Address", or "Network Adapter Address". The Wireless ADSL2/2+ Modem Router uses this to provide a unique identifier for each PC. Because of this, the MAC address can NOT be left blank.

Logs

The Logs record various types of activity on the Wireless ADSL2/2+ Modem Router. This data is useful for troubleshooting, but enabling all logs will generate a large amount of data and adversely affect performance.
Since only a limited amount of log data can be stored in the Wireless ADSL2/2+ Modem Router, log data can also be E-mailed to your PC. Use the E-mail screen to configure this feature.

boxes)
There are three (3) buttons
Refresh - Update the log data.
Clear Log - Clear the log, and restart it. This makes
new messages easier to read.
Send Log - E-mail the log immediately. This is only functional if the E-mail screen has been configured.
Use these checkboxes to determine which events are included in the log. Checking all options will increase the size of the log, so it is good practice to disable any events which are not really required.
Attempted access to blocked sites - If checked, attempted Internet accesses which were blocked are logged.
Connections to the Web-based interface of this Router - If checked, this will log connections TO this
Router, rather than through this Router to the Internet.
Router operation - If checked, other Router operations (not covered by the selections above) will be logged.
Known DoS attacks and Port Scans - If checked, Denial of Service attacks, as well as port scans, will be logged.
Syslog Disable Broadcast on LAN
Syslog Server
Data is not sent to a Syslog Server. The Syslog data is broadcast, rather than sent to a specific
Syslog server. Use this if your Syslog Server does not have a fixed IP address.
If your Syslog server has a fixed IP address, select this option, and enter the IP address of your Syslog server.
