Gateway User Interface 19 Using Broadband Link Advanced Settings The Advanced Settings page allows you to manually configure your DSL and Internet connection settings. Typically, these settings are automatically provided by your service provider. You should adjust these settings ONLY if you are ver y familiar with DSL and networking technology. Selecting Broadband Connection. The Broadband Type dro pdown menu allows you to select whether to connect via DSL or Ethernet. Modifying DSL Settings. When your gateway is config ured to use DSL, the gateway can be configured as to which DSL line port to use. By default, the gatewa y automatically detects which DSL line to use. The DSL Line Selection dropdown menu allows you to se lect a DSL line (Automatic, RJ-11, or CoAX).
Gateway User Interface 20 Home Network Pages Viewing Your Home Network Summar y The Home Network Summary page displays information about the devices installed on your network. Local Devices The Local Devices panel shows you the name of the devic e, how it is connected, any special configuration information, and provides links to other system featur es that you can set up for the device. A “device” on your network is usually a computer — either a personal computer used by a household member, or a computer that is dedicated to a specific use (such as a Web server that hosts online games). The status of each device is shown in the Local Devices list. Each device on your home network is represented with a computer icon. If the “show inactive devices” option is enabled, and the device becomes inactive because it is powered off or removed from your network, this icon will display as Inactive. If you defined a name for your computer during System Setup or when your computer was set up, the name displays next to the device. However, there are two instances where the device name will not appear: If your computer was manually configured with a st atic IP address, the static IP address displays instead of the computer’s name. If you have not named the device but it still obtai ns its Internet address from the system, the word “Unknown” displays. If you have configured the firewall to allow informati on from the Internet to pass through to the computer (also referred to as “hosting an application”), the name of the applicat ion(s) that you are hosting are displayed under the device name. Depending on the permissions you have set for devices on your network, the following links may display next to the device:
Gateway User Interface 21 Access shared files. Accesses the shared files available from this computer. This feature only works with Microsoft Windows computers that have shared files and file sharing installed. If your computer is configured with a static IP addr ess, this link will not appear. Edit firewall settings. Accesses the system user in terface page, which allows you to edit the firewall pass-through settings for the computer. For exampl e, you may need to change the pass-through settings for the computer if you want to play an Internet game. View Internet Access Control. Accesses the Inte rnet Access Restriction schedule for this computer. Edit Content Screening. Accesses the Content Screeni ng settings page, allowing you to change the Web site permissions for users on your network. View device details. Displays the technical networki ng details about the device. This information may be helpful to a technical suppor t representativ e if you are experiencing difficulties. Note: Depending on the enhanced ser vices offered by your service provider, some links (such as Internet Access Control or Content Screening) may not be available. Status at a Glance Panel The Status at a Glance panel shows you a list of network connection types, the number of devices connected via each connection type, and your wireless sett ings. To change your wireless settings, click the EDIT SETTINGS button. To disable a network device, click the DISABLE button. Monitoring Your Wireless Settings Your 2Wire gateway has an integrated wireless access point, which enables you to connect your wireless- enabled computers to your home network.
Gateway User Interface 22 By default, the 2Wire gateway ships with WPA enabled and a preconfigured network name. The default WPA key is located on the bottom of the gateway, next to the serial number. The Current Settings panel shows the 2Wire ga teway’s wireless access point settings: Access Point. The designated name of the wireless access point. Network Name. The name assigned to your wire less network. The default is 2WIREXXX, where XXX represents the last three digits of your 2Wir e gateway serial number (for example, 2WIRE954). Channel. The radio frequency band the access point uses for your wireless network (the default is 6). Wireless adapter cards auto-detect which channels to use. If you are having problems with your wireless network, it could be due to radio interferenc e. You can change the wireless channel to see if interference is reduced on a different channel. Authentication. The security method used to ensur e that users are authorized to access the wireless network: WEP - Open, WEP - Shared, or WPA-PSK. Encr yption. The security setting that makes it difficult for unauthorized users to access your network.
Gateway User Interface 23 Customizing Security Settings You should always enable encr yption for wireless communication. When encryption is enabled, you must define an encr yption key for the 2Wire gateway’s wirele ss access point and configure that same key on each wireless client that will use your 2Wire gateway wireless network. Note: If encr yption is enabled, each wireless client must be configured with the encr yption key defined on the system before it can operate on your wireless network. Configuring Additional Settings The Additional Settings panel allows you to cust omize wireless settings. In general, it is recommended that you leave the default settings in place; however, if you are experiencing connection or performance difficulties, alteri ng these settings may improve performance. Note: Because the fields that display are dependent on the type of wireless adapter you are using, some of these settings may not display. Wireless Mode. Allows you to force the gate way to use 802.11b/g, 802.11b-only, or 802.11g-only modes of operation. DTIM Period (seconds). Determines at which inter val the access point will send its broadcast traffic. This field displays only for 802.11b/g based models. Maximum Connection Rate. The maximum rate at which your wireless connection works (1, 2, 5.5, 11, or 22 Mbps for 802.11b-based models; 1, 2, 5.5, 11, 6, 9, 12, 24, 36, 48, or 54 Mbps for 802.11b/ g-based models). Power Setting. Allows you to select the power leve l for your wireless connection. Power level options are based on the ser vice provider’s configuration. If you have customized your wireless system configurat ion, you can restore the wireless settings to factor y defaults by clicking the RESTORE DEFAULTS button.
Gateway User Interface 24 Configuring Advanced Settings The Edit Advanced Home Network Settings page displays the current IP settings in use by your system for your home network, and allows you to configure your home network settings. You should adjust these settings ONLY if you are ver y familiar with computer networking technologies. The Current Settings panel shows the following information: Router Address. The IP address used by your ga teway on the private home network (the default is 192.168.1.254). The gateway has two IP addresses: a private address that it uses on the home network, and one that is used on the public broadband connection on the Internet. You can change the home network IP address by changing the home network IP address range. Subnet Mask. The subnet mask is determined by the home network IP address range settings (the default is 255.255.255.0). DHCP Range. The range of IP addresses used by your system (the default is 192.168.1.33 through 192.168.1.250). IP addresses can be either static ( permanently assigned) or dynamic (automatic and temporary).
Gateway User Interface 25 Editing Address Allocation Settings The Current Settings panel displays the computers curr ently on the local network, and their IP address. It also indicates whether a given computer is receiv ing its IP address via DHCP or has been manually entered into the computer (static). If users enable the Public Network feature, they can choose to have their broadband accessible (non-NAT) IP addresses assigned automatically via DHCP to computers on the local network. To do so: 1.Click the Edit Address Allocation button. The Edit Address Allocation Settings page opens. 2.In the Settings panel, select an available IP addres s from the pulldown menu next to the computer to which you want an IP addres s automatically assigned. 3.Click Save. Users can choose to have the address assigned from an y of the available networks. Computers that are assigned non-routable (private network ) addresses will use Network Address Translation (NAT) to access the internet. Selecting a “DHCP Fixed” entry instructs the gateway to always provide the same address from the DHCP pool to the specified computer. Computers on the Public Network are still behind the fire wall. To allow inbound traffic to these computers, the firewall settings specified for that computer must be modified.
Gateway User Interface 26 Firewall Pages The 2Wire gateway has a professional-grade firewall to help prevent unauthorized users from accessing your local network. The 2Wire gateway firewall includes the following features: Stateful packet inspection. Blocks common Denial of Ser vice attacks (such as SYN/FIN flooding or Smurf), and detects and logs TCP and UDP port scans. Stateless packet inspection. Filters specific NetB ios traffic, suspicious packets and IP fragments; blocks packets sent from the private network to the Internet that have spoofed IP addresses. Network Address Translation (NAT). Translates a lo cal network’s IP address to an external address maintained by the 2Wire gateway, effectively “hiding” the existence of a home network to the Internet. The 2Wire gateway then uses this external addre ss to communicate with the Internet on behalf of devices connected to the local network. Por t Address Translation (PAT). A function provided by some routers which allows hosts on a LAN to communicate with the rest of a network (such as t he Internet) without revealing their own private IP address. All outbound packets have their IP address tr anslated to the router’s external IP address. Replies come back to the router, which then transla tes them back into the private IP address of the original host for final deliver y. During PAT, each computer on the LAN is translated to the same IP address, but with a different port number assignment. Inbound and outbound port blocking. Blocks comm on inbound and outbound protocol types from passing information to or receiving information from the Internet. Viewing Your Firewall Summar y The Firewall Summary page provides summar y informat ion and links to the most commonly used security- related features of your system.
Gateway User Interface 27 The Firewall Settings panel displays the Current Settings for your firewall. Default. Unsolicited inbound traffic is not allowed to pass through the firewall. Custom. Applications are associated with computers on your network. An access list shows the computers (Devices) on your network and the names of the Allowed Applications for each computer. When you allow application traffic, external users on the Internet can have limited access to your home network. This access might be required to allow some programs (such as game ser vers or instant messaging software) to operate properly. For example, a remote game player on the Internet mi ght need to contact the game server program that you have installed on your home network in order to play against you. Normally, the firewall blocks this communication. By changing the firewall settings, this communication is permitted to pass through a “pinhole” in the firewall. This function may be referred to as “port-mapping” or “por t-forwarding” in your software program documentation. Click VIEW DETAILS to access the Firewall Details page, which shows a list of all the devices that have applications configured in the firewall and the details of these configurations.
Gateway User Interface 28 Configuring Firewall Settings The Edit Firewall Settings page allows you to open select por ts, or “pinholes” in the firewall. You can allow individual applications, or use DMZplus mode. When in DMZplus mode, the designated computer: Shares your gateway’s IP address (Router Address). Appears as if it is directly connected to the Internet. Has all of the unassigned TCP and UDP por ts opened and pointed to it. Can receive unsolicited network traffic from the Internet. Because all filtered traffic is forwarded to the desig nated computer, you should use DMZplus mode with caution. A computer in DMZplus mode is less secu re because all available ports are open and all incoming Internet traffic is directed to this computer.
