Wireless-N ADSL2+ Gateway Chapter 2: Planning Your Network The Gateway’s Functions A Gateway is a network device that connects two networks together. In this instance, the Gateway connects your Local Area Network (LAN), or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks. The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers.
Wireless-N ADSL2+ Gateway Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Gateway. You can get that information from your ISP. Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.
Wireless-N ADSL2+ Gateway Chapter 3: Getting to Know the Wireless-N ADSL2+ Gateway Ports and Reset Button on Back Panel The Gateway’s ports and Reset button are located on a side panel. Figure 3-1: Ports and Reset Button on Side Panel Internet The Internet port connects to the ADSL line. Ethernet (1-4) The Ethernet ports connect to your computers and other network devices. Reset Button There are two ways to reset the Gateway's factory defaults.
Wireless-N ADSL2+ Gateway LEDs on Front Panel The Gateway's LEDs, which indicate network activity, are located on the front panel. Figure 3-2: LEDs on Side Panel POWER Green. The POWER LED lights up when the Gateway is powered on. ETHERNET (1-4) Green. The ETHERNET LED serves two purposes. If the LED is continuously lit, the Gateway is successfully connected to a device through the Ethernet port. If the LED is flashing, it is an indication of any network activity. DSL Green.
Wireless-N ADSL2+ Gateway Chapter 4: Connecting the Wireless-N ADSL2+ Gateway Overview The installation technician from your ISP should have left the setup information with you after installing your broadband connection. If not, you can call your ISP to request that data. After you have the setup information you need for your specific type of Internet connection, you can begin installation and setup of the Gateway.
Wireless-N ADSL2+ Gateway Wireless Connection to a Computer If you want to use a wireless connection to access the Gateway, follow these instructions: 1. Make sure that all of your network’s hardware is powered off, including the Gateway and all computers. 2. Connect a phone cable from the DSL port on the Gateway’s back panel to the wall jack of the ADSL line. A small device called a microfilter (not included) may be necessary between each phone and wall jack to prevent interference.
Wireless-N ADSL2+ Gateway Chapter 5: Configuring the Wireless-N ADSL2+ Gateway Overview Follow the steps in this chapter and use the Gateway’s Web-based Utility to configure the Gateway. This chapter will describe each web page in the Utility and each page’s key functions. The utility can be accessed via your web browser through use of a computer connected to the Gateway.

Your ISP will provide you with the Subnet Mask. • Default Gateway. Your ISP will provide you with the default Gateway Address, which is the ISP server’s IP address.
Wireless-N ADSL2+ Gateway RFC 2516 PPPoE Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections. If you are connected to the Internet through a DSL line, check with your ISP to see if they use PPPoE. If they do, you will have to enable PPPoE. • User Name and Password. Enter the User Name and Password provided by your ISP. • Connect on Demand: Max Idle Time.
Wireless-N ADSL2+ Gateway Bridge Mode Only If you are using your Gateway as a bridge, which makes the Gateway act like a stand-alone modem, select Bridge Mode Only. All NAT and routing settings are disabled in this mode. Optional Settings (required by some ISPs) • Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway. Some ISPs require these names as identification.
Wireless-N ADSL2+ Gateway • Client Lease Time. The Client Lease Time is the amount of time a computer will be allowed connection to the Gateway with its current dynamic IP address. Enter the amount of time, in minutes, that the computer will be “leased” this dynamic IP address. • Static DNS 1-3. The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address.
Wireless-N ADSL2+ Gateway The DDNS Tab The Gateway offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Gateway. Before you can use this feature, you need to sign up for DDNS service at DynDNS.org or TZO.com.

Wireless-N ADSL2+ Gateway The Applications and Gaming Tab The Single Port Range Forwarding Tab Use the Single Port Range Forwarding screen when you want to open a specific port so users on the Internet can see the servers behind the Gateway (such servers may include FTP or e-mail servers). When users send this type of request to your network via the Internet, the Gateway will forward those requests to the appropriate computer.
Wireless-N ADSL2+ Gateway The Port Range Forwarding Tab The Port Range Forwarding screen sets up public services on your network, such as web servers, ftp servers, email servers, or other specialized Internet applications. (Specialized Internet applications are any applications that use Internet access to perform functions such as videoconferencing or online gaming. Some Internet applications may not require any forwarding.
Wireless-N ADSL2+ Gateway The Port Triggering Tab Port Triggering is used for special applications that can request a port to be opened on demand. For this feature, the Gateway will watch outgoing data for specific port numbers. The Gateway will remember the IP address of the computer that sends a transmission requesting data, so that when the requested data returns through the Gateway, the data is pulled back to the proper computer by way of IP address and port mapping rules.
Wireless-N ADSL2+ Gateway The DMZ Tab The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10 ranges of ports. DMZ • DMZ Hosting.
Wireless-N ADSL2+ Gateway The QoS Tab QoS (Quality of Service) QoS ensures better service to high-priority types of network traffic, which may involve demanding, real-time applications, such as Internet phone calls or videoconferencing. Wireless • ACK Mode. This setting prioritizes QoS for users who also have ACK Mode enabled. Users with Immediate ACK (the default setting) will experience reliable connectivity for normal network use.
