1 Chapter 1 Introduction This Chapter provides an overview of the 802.11g ADSL VoIP Gateway's fea-tures and capabilities. Congratulations on the purchase of your new 802.11g ADSL VoIP Gateway. The 802.11g ADSL VoIP Gateway is a multi-function device providing the following services: • ADSL Modem. • Shared Broadband Internet Access (NAT Router) for all LAN & WLAN users. • Wireless Access Point for 802.11b and 802.11g Wireless Stations. • VoIP Gateway supporting the industry-standard SIP protocol. • 4-Port Ethernet Port for 10BaseT or 100BaseT connections. Figure 1: 802.11g ADSL VoIP Gateway 802.11g ADSL VoIP Gateway Features The 802.11g ADSL VoIP Gateway 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 802.11g ADSL VoIP Gateway, 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 ADSL Modem. The 802.11g ADSL VoIP Gateway has a built-in ADSL modem, supporting all common ADSL connections. • IPoA, PPPoE, PPPoA, Direct Connection Support. The 802.11g ADSL VoIP Gateway supports all common connection methods. 1
802.11g ADSL VoIP Gateway User Guide 2 • Auto-detection of Internet Connection Method. In most situations, the 802.11g ADSL VoIP Gateway can test your ADSL and Internet connection to determine the connec-tion method used by your ISP. • Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the 802.11g ADSL VoIP Gateway supports both Dynamic IP Address (IP Address is allocated on con-nection) and Fixed IP Address. Advanced Internet Functions • Application Level Gateways (ALGs). Applications which use non-standard connec-tions 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 dy-namic 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. VoIP Features • SIP Standard Compatible. The Wireless VoIP Gateway complies with the SIP standard for VoIP. • Advanced Call features. Caller ID, Caller name, Call waiting, three-way conference call, DTMF relay, Voice active detection, Echo canceller. • FAX Support. Both the T.38 and G.711 Fax standards are supported, allowing both sending and receiving faxes via the Wireless VoIP Gateway. • Life line (PSTN fallback) Support. The PSTN (analogue phone) port is automatically used when the Internet connection is not operational or there is a power failure. Wireless Features • Standards Compliant. The 802.11g ADSL VoIP Gateway 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.
Introduction 3 • Speeds up and exceeding 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported. Also, the 802.11g ADSL VoIP Gateway support TI's proprietary "g-Plus" solution, which allows even faster speeds between compatible wireless devices. • 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 pro-tection against snoopers. • WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission, 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 Ethernet Switching Hub. The 802.11g ADSL VoIP Gateway incorporates a 4-port 10/100BaseT switching hub. • DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The 802.11g ADSL VoIP Gateway 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 configura-tion. • Configuration File Upload/Download. Save (download) the configuration data from the 802.11g ADSL VoIP Gateway to your PC, and restore (upload) a previously-saved configuration file to the 802.11g ADSL VoIP Gateway. • Remote Management. The 802.11g ADSL VoIP Gateway can be managed from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (option-ally) be configured via the Internet. • Network Diagnostics. You can use the 802.11g ADSL VoIP Gateway 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 ad-dress 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) tech-nology 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 802.11g ADSL VoIP Gateway. • Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources.
802.11g ADSL VoIP Gateway User Guide 4 • Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much band-width and so many resources that Internet access becomes unavailable. The 802.11g ADSL VoIP Gateway incorporates protection against DoS attacks.

802.11g ADSL VoIP Gateway User Guide 16 LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below. Figure 6: LAN Screen Data - LAN Screen TCP/IP IP Address IP address for the 802.11g ADSL VoIP Gateway, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. Subnet Mask The default value 255.255.255.0 is standard for small (class "C") net-works. For other networks, use the Subnet Mask for the LAN segment to which the 802.11g ADSL VoIP Gateway is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the 802.11g ADSL VoIP Gateway will allocate IP Ad-dresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. • If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the 802.11g ADSL VoIP Gateway as the default Gateway. See the following section for further details. • The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP. 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.
Setup 17 • The 802.11g ADSL VoIP Gateway 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 802.11g ADSL VoIP Gateway'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 802.11g ADSL VoIP Gateway'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 802.11g ADSL VoIP Gateway's, the following procedure is required. • Disable the DHCP Server feature in the 802.11g ADSL VoIP Gateway. This setting is on the LAN screen. • Configure the DHCP Server to provide the 802.11g ADSL VoIP Gateway'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 - PC Configuration for the procedure to check these settings.
802.11g ADSL VoIP Gateway User Guide 18 Wireless Screen The 802.11g ADSL VoIP Gateway's settings mu st match the other Wireless stations. Note that the 802.11g ADSL VoIP Gateway will automatically accept both 802.11b and 802.11g connections, and no configuration is required for this feature. To change the 802.11g ADSL VoIP Gateway's default settings for the Wireless Access Point feature, use the Wireless link on the main menu to reach the Wireless screen. An example screen is shown below. Figure 7: Wireless Screen Data - Wireless Screen Identification Region Select the correct domain for your location.

There are 3 options for Wireless security: • Disabled - no data encryption is used. • WEP - data is encrypted using the WEP standard. • WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP. WEP Wireless Security Figure 8: WEP Data - WEP Screen WEP Data Encryption WEP Data En-cryption Select the desired option, and ensure the Wireless Stations use the same setting. • 64 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 64 Bit En-cryption, the key size is 10 chars in HEX (0~9 and A~F). • 128 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 128 Bit En-cryption, the key size is 26 chars in HEX (0~9 and A~F). Authentication Type Normally, this should be left at the default value of "Automatic". If changed to "Open System" or "Shared Key", ensure that your Wireless Stations use the same setting. Default Key Select the key you wish to be the default. Transmitted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only. You must enter a Key Value for the Default Key.
802.11g ADSL VoIP Gateway User Guide 22 Key Value Enter the key value or values you wish to use. The Default Key is required, the other keys are optional. Other stations must have the same key. Passphrase If desired, you can generate a key from a phrase, instead of entering the key value directly. Enter the desired phrase, and click the "Generate Keys" button. WPA-PSK Wireless Security Figure 9: WPA-PSK Data - WPA-PSK Screen Security System WPA-PSK Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should be used if possible. WPA-PSK is the version of WPA, which does NOT require a Radius Server on your LAN. PSK Enter the PSK (network key). Data is encrypted using a key derived from the network key. Other Wireless Stations must use the same network key. The PSK must be from 8 to 63 characters in length. WPA Encryption The WPA-PSK standard allows different encryption methods to be used. Select the desired option. Wireless Stations must use the same encryption method.
