Chapter 1 Introduction 1.1 Introducing the myGuard 7202(G) Thank you for purchasing the myG uard 7202(G) ADSL Router by Bi llion. Y our new router is an all-in-one unit that combines an ADSL m odem, A.
addresses making them invisible to outside users on the Internet, so it is much more dif ficult for a hacker to target a machine on your network . Second, it can block and redirect cert ain ports to limit the services that out side users can access.
1.2 Features Express Internet Access – ADSL2/2+ cap able The myGuard 7202(G) complies with ADSL worldwide standards. Supporting downstream rates of 8Mbps with ADSL, the myGuard rout er is capable of up to 12/24 Mbps with ADSL2/2+, and upstream rates of up to 1 Mb ps.
and PCs from many different vendors, and it makes setting up a network simple and affordable. UPnP architecture leverages TCP/IP and the Web to enable proximity networking in addition to control and data transfer among networked devices. With this feature enabled, you can seamlessly connec t to Net Meeting or MSN Messenger.
V irtual Server: You can specify which services are visible to outside users. The myGuar d router detects an incoming service request and forwards it to t he specific local computer for handling. For example, you can assign a PC in a LAN to ac t as a Web server inside and expose it to the outside network.

4.3 Configuration Click this item to access the following sub- items that configur e the ADSL router: LAN, W AN, System, Firewall, QoS, V irtual Server and Advanced.
4.3.1 LAN (Local Area Network) 4.3.1 LAN (Local Area Network) A Local Area Network (LAN) is a shared comm unication system to which many computers are attached and is limited to t he immediate area, usually the same building or floor of a building.
4.3.1.2 Wireless Parameters Mode: 802.1 1b + g (Mixed mode), 802.1 1b and 802.1 1g. The factory default is 802.1 1b + g. ESSID: Enter the unique ID given to the Access Poin t (AP), which is already built-in to the router ’s wireless interface. T o connect to this device, your wireless clients must have the same ESSID as the device.
WDS Service: The default setting is Disable. Check Enable radio button to activate this function. Peer WDS MAC Address: It is the associated AP’s MAC Address. It is important that your peer ’s AP must include your MAC address in order to acknowledge and communicate with each other .
WEP WEP Encryption: T o prevent unauthorized wireless stations from accessing data transmitted over the network, the router offers highly secure data encryption, known as WEP . If you require high security for transmissions, t here are two alternativ es to select from: WEP 64 and WEP 128 .

If you check DHCP Relay Agent and click Next then you must enter the IP address of the DHCP server which assigns an IP address back to the DHCP client in the LAN. Use this function only if advised to do so by your network administr ator or ISP . Click Appl y to enable this function.
4.3.2 W AN (Wide Area Network) A W AN (Wide Area Network) is an outside connec tion to another network or the Internet. There are three items within the W AN section: ISP , DNS and ADSL. 4.3.2.1 ISP The factory default is PPPoE. If your IS P uses this access protocol, click Edit to input other parameters as below .
NA T: The NA T (Network Address T ranslation) feat ure allows multiple users to access t he Internet through a single IP account, sharing the single IP address. If users on your LAN have public IP addresses and can access the Inte rnet directly , the NA T function can be disabled.
NA T: The NA T (Network Address T ranslation) feat ure allows multiple users to access t he Internet through a single IP account, sharing a single IP address. If users on your LAN have public IP addresses and can access the Internet directly , the NA T function can be disabled.
Description: A user-definable name for this connection. VPI/VCI: Enter the information provided by your ISP . NA T: The NA T (Network Address T ranslation) feat ure allows multiple users to access t he Internet through a single ISP account, shari ng a single IP address.
and to automatically re-establish the PPPo E session when disconnected by the ISP . Connect to Demand: If you want to establish a PPPoE session only when there is a packet requesting access to the Internet (i.e. when a program on your computer attempts to access the Internet).
4.3.2.2 DNS A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet, every host has a unique and user-friendl y name (domain name) such as www .billion.com and an IP address. An IP address is a 32-bit number in the form of xxx.
4.3.2.3 ADSL ADSL Mode: There are four modes “Open Annex T y pe and Follow DSLAM’s Setting”, ”Annex A Only”, ”Annex L Only” and ”Annex M Only” that user can select for this connection.

If you wish to restart the rout er using the factory default se ttings (for example, af ter a firmware upgrade or if you have saved an incorrect configuration), select Factory Default Settings to reset to factory default settings.
Y ou can change the user ’s p assword , whether their account is active and Va l i d , as well as add a comment to each user account. These opt ions are the same when creating a user account, with the exception that once creat ed you cannot change the username.
4.3.4 Firewall 4.3.4 Firewall Firewall and Access Control Firewall and Access Control Y our router includes a full SPI (S tateful Packet Inspection) firewall for controlling Internet access from your LAN, as well as helping to pr event attacks fro m hackers.
prevent unauthorized computers or applications accessing your local network from the Internet. Intrusion Detection : Enable Intrusion Detection to detect, prevent, and log malicious attacks. MAC Filter rules : Prevents unauthorized computers accessing the Internet.
4.3.4.1 Packet Filter Packet filtering enables you to configure your router to block specified internal/external users ( IP a ddress ) from Internet access, or you can disable specific service requests ( Po rt number ) to /from Internet.
Application: User can choose that they want. Outgoing Incoming: Determine whether the rule is for outgoing p ackets or for incoming packet s. Active: Choose “Y es” to enable the rule, or choose “No” to disable the rule. Packet T ype: S pecify the packet type (TCP , UDP , ICMP or any) that the rule applies to.
Schedule time: User can setup the time to use the packet filter. A ttention If the DHCP server option is enabled, y ou must be very careful in assigning IP addresses of a filtered private IP range to avoid conflicts because you do not know which PC in the LAN is a ssigned which IP address.
Active: Select Yes from the drop down list box to enable MAC address filtering. Action When Matched: Select “Drop” or “Forward”. Log: Choose “Y es” if you wish to generate logs when the filer rule is applied to a pa cket. MAC Address: Enter the MAC addresses you wish to manage.
4.3.4.3 Intrusion Detection Check “Enable” if you wish to detect intruders accessing your computer without permission. The myGuard router autom atically detects and blocks a DoS (D enial of Service) attack if a user enables this function.
Alert Mail Time: Set the time for receiving Alert mail. Your E-Mail: Set your email address. Recipient’s E-mail: Set the Recipient’s email address to which the E-<mail notification is sent. SMTP server: Set the SMTP (mail) server address. 4.3.4.
