These PCs can still communicate with each other on your LAN, but traffic they originate to the WAN is blocked by the gateway. Fig. 19 Gateway\Advnaced\IP Filtering
Chapter 2: Web Configuration 33 Illustrations contained in this document are for representation only. 3. MAC Filtering This page enables you to enter the MAC address of specific PCs on your LAN that you wish to NOT have outbound access to the WAN. As with IP filtering, these PCs can still communicate with each other through the gateway, but packets they send to WAN addresses are blocked. Fig. 20 Gateway\Advnaced\MAC Filtering
Chapter 2: Web Configuration 34 Illustrations contained in this document are for representation only. 4. Port Filtering This page allows you to enter ranges of destination ports (applications) that you don’t want your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked. For example, you could block access to worldwide web browsing (http = port 80) but still allow email service (SMTP port 25 and POP-3 port 110). To enable port filtering, set Start Port and End Port for each range, and click Apply. To block only one port, set both Start and End ports the same. Fig. 21 Gateway\Advnaced\Port Filtering
Chapter 2: Web Configuration 35 Illustrations contained in this document are for representation only. 5. Forwarding For LAN  WAN communications, the gateway normally only allows you to originate an IP connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the destination port (application) matches one you specify. This page allows you to specify up to 10 such rules. For example, to specify that outsiders should have access to an FTP server you have running at 192.168.0.5, create a rule with that address and Start Port =20 and End Port =21 (FTP port ranges) and Protocol = TCP (FTP runs over TCP and the other transport protocol, UDP), and click Apply. This will cause inbound packets that match to be forwarded to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the Connection Table. The same IP address can be entered multiple times with different ports. Fig. 22 Gateway\Advnaced\Forwarding
Chapter 2: Web Configuration 36 Illustrations contained in this document are for representation only. 6. Port Triggers Some Internet activities, such as interactive gaming, require that a PC on the WAN side of your gateway be able to originate connections during the game with your game playing PC on the LAN side. You could use the Advanced-Forwarding web page to construct a forwarding rule during the game, and then remove it afterwards (to restore full protection to your LAN PC) to facilitate this. Port triggering is an elegant mechanism that does this work for you, each time you play the game. Fig. 23 Gateway\Advnaced\Port Triggers Port Triggering works as follows. Imagine you want to play a particular game with PCs somewhere on the Internet. You make one time effort to set up a Port Trigger for that game, by entering into Trigger Range the range of destination ports your game will be sending to, and entering into Target Range the range of destination ports the other player (on the WAN side) will be sending to (ports your PC’s game receives on). Application programs like games publish this information in user manuals. Later, each time you play the game, the gateway automatically creates the forwarding rule necessary. This rule is valid until 10 minutes after it sees game activity stop. After 10 minutes, the rule becomes inactive until the next matched outgoing traffic arrives. For example, suppose you specify Trigger Range from 6660 to 6670 and Target Range from 113 to 113. An outbound packet arrives at the gateway with your game-playing PC source IP address 192.168.0.10, destination port 666 over TCP/IP. This destination port is within the Trigger destined for port 113 to your game-playing PC at 192.168.0.10. You can specify up to 10 port ranges on which to trigger.

DMZ Host Use this page to designate one PC on your LAN that should be left accessible to all PCs from the WAN side, for all ports. For example, if you put an HTTP server on this machine, anyone will be able to access that HTTP server by using your gateway IP address as the destination. A setting of “0” indicates NO DMZ PC. “Host” is another Internet term for a PC connected to the Internet. Fig. 24 Gateway\Advnaced\DMZ Host
Chapter 2: Web Configuration 38 Illustrations contained in this document are for representation only. 8. RIP (Routing Information Protocol) Setup This feature enables the gateway to be used in small business situations where more than one LAN (local area network) is installed. The RIP protocol provides the gateway a means to “advertise” available IP routes to these LANs to your cable operator, so packets can be routed properly in this situation. Your cable operator will advise you during installation if any setting changes are required here. Fig. 25 Gateway\Advnaced\RIP Setup

Gateway – Wireless Web Page Group Important: Changes to the wireless web pages should be made from a PC that is directly connected to the gateway. The Wireless web pages group enables a variety of settings that can provide secure and reliable wireless communications for even the most demanding tech-savvy user. The DWG855 gateway offers a choice of 802.1x, WPA and WPA-PSK authentication of your PCs to the gateway, 64 and 128 bit WEP encryption of communication between the gateway and your PCs to guaranty security, and an Access Control List function that enables you to restrict wireless access to only your specific PCs. The wireless function will probably work in your home as shipped from the factory, but without the security features activated. In addition, the factory default wireless channel setting may not provide optimum changes are recommended from the factory defaults, to secure your wireless communications and provide optimum performance. Performance Because your wireless communication travels through the air, the factory default wireless channel setting may not provide optimum performance in your home if you or your neighbors have other interfering 2.4GHz devices such as cordless phones. If your wireless PC is experiencing very sluggish or dramatically slower communication compared with the speed you achieve on your PC that is wired to the gateway, try changing the channel number. See the 802.11b/g Basic Web Page discussion below for details. Authentication Authentication enables you to restrict your gateway from communicating with any remote wireless PCs that aren’t yours. The following minimum authentication-related changes to factory defaults are recommended. See the 802.11b/g Basic and Access Control Web Page discussions below for details. Network Name (SSID) – Set a unique name you choose Network Type – Set to Open Access Control List – Enter your wireless PCs’ MAC addresses Security Security secures or scrambles messages traveling through the air between your wireless PCs and the gateway, so they can’t be observed by others. The following minimum security setting changes to factory defaults are recommended. See the 802.11b/g Security Web Page discussion below for details.

The gateway WiFi radio frequently transmits a beacon signal which can contain this network name (SSID). If you set Closed
Chapter 2: Web Configuration 46 Illustrations contained in this document are for representation only. Network to Enable, your SSID is included in that beacon, and is therefore detectable by any nearby wireless equipped PCs in the area. The benefit of using Enable is it can speed your WiFi setup on some PCs. If you set Closed Network to Disable, your SSID is not included in the beacon. This hides your network name (SSID), but as a result may require a bit more effort on your part to set up your wireless PCs. And when we Enable the WPS Config then the Closed Network will be Disabled automatically. WPA (Wi-Fi Protected Access)/WPA2: It must be used in conjunction with an authentication server such as RADIUS to provide centralized access control and management. It can provide stronger encryption and authentication solution than none WPA modes. WPA2 is the second generation of WPA security WPA-PSK (WPA-Pre-Shared Key) /WPA2-PSK (WPA2-Pre-Shared Key): It is useful for small places without authentication servers such as the network at home. It allows the use of manually-entered keys or passwords and is designed to be easily set up for home users. WEP Encryption: You can choose 64-bit or 128-bit according to your needs. If you choose Disabled, the Network Keys will not be shown on this page. If selected, the data is encrypted using the key before being transmitted. For example, if you set 128-bit in this field, then the receiving station must be set to use the128 Bit Encryption, and have the same Key value too. Otherwise, it will not be able to decrypt the data. ( Note: You need to connect one end of the Ethernet cable to the Ethernet port on the back of your computer, and the other end to the ETHERNET port on the Residential Voice Gateway. )  If you select WEP (64-bit or 128-bit), you can adjust the following settings-  Shared Key Authentication: Decide whether to set the shared key Optional or Required by selecting from the drop-down menu.  Network Key 1 to 4: The system allows you to enter four sets of the WEP key.

What if I don’t subscribe to cable TV? A. If cable TV is available in your area, data and voice service may be made available with or without cable TV service. Contact your local cable company for complete information on cable services, including high-speed internet access. Q. How do I get the system installed? A. Professional installation from your cable provider is strongly recommended. They will ensure proper cable connection to the modem and your computer. However, your retailer may have offered a self installation kit, including the necessary software to communicate with your cable ISP. Q. Once my Residential Voice Gateway is connected, how do I get access to the Internet? A. Your local cable company provides your internet service*, offering a wide range of services including email, chat, and news and information services, and a connection to the World Wide Web. Q. Can I watch TV, surf the Internet, and talk to my friends through the Residential Voice Gateway at the same time? A. Absolutely! Q. What do you mean by “Broadband?” A. Simply put, it means you’ll be getting information through a “bigger pipe,” with more bandwidth, than a standard phone line can offer. A wider, “broader” band means more information, more quickly. Q. What is DOCSIS and what does it mean? A. “Data over Cable Service Interface Specifications” is the industry standard that most cable companies are adopting as they upgrade their systems. Should you ever decide to move, the Residential Voice Gateway will work with all upgraded cable systems that are DOCSIS-compliant. Q. What is PacketCable and what does it mean? A. Like DOCSIS, PacketCable is the industry standard for telephony services that most cable companies are adopting as they upgrade their systems. Should you ever decide to move, the Residential Voice Gateway will work with all upgraded cable systems that are PacketCable-compliant. Q. What is Xpress Technology and what does it mean?
Chapter 3: Additional Information 66 Illustrations contained in this document are for representation only. A. It is one of the popular performance-enhancing WiFi technologies, designed to improve wireless network efficiency and boost throughput. It is more efficient in mixed environments, and it can work with 802.11a/b/g networks. When Xpress is turned on, aggregate throughput (the sum of the individual throughput speeds of each client on the network) can improve by up to 27% in 802.11g-only networks, and up to 75% in mixed networks comprised of 802.11g and 802.11b standard equipment. The technology achieves higher throughput by re-packaging data, reducing the number of overhead control packets, so that more useful data can be sent during a given amount of time. * Monthly subscription fee may apply. ** Additional equipment required. Contact your Cable Company and ISP for any restrictions or additional fees.

General Troubleshooting You can correct most problems you have with your product by consulting the troubleshooting list that follows. I can’t access the internet.  Check all of the connections to your Residential Voice Gateway.  Your Ethernet card may not be working. Check each product’s documentation for more information.  The Network Properties of your operating system may not be installed correctly or the settings may be incorrect. Check with your ISP or cable company. All or some of the lights are flashing in sequence.  This means the Residential Voice Gateway is automatically updating its system software. Please wait for the lights to stop flashing. The updating process typically lasts less than one minute.  Do not remove the power supply or reset the Residential Voice Gateway during this process. I can’t get the modem to establish an Ethernet connection.  Even new computers don’t always have Ethernet capabilities – be sure to verify that your computer has a properly installed Ethernet card and the driver software to support it.  Check to see that you are using the right type of Ethernet cable. The modem won’t register a cable connection.  If the modem is in Initialization Mode, the INTERNET light will be flashing. Call your Cable Company if it has not completed this 5-step process within 30 minutes, and note which step it is getting stuck on. (See page 22 for details.)  The modem should work with a standard RG-6 coaxial cable, but if you’re using a cable other than the one your Cable Company recommends, or if the terminal connections are loose, it may not work. Check with your Cable Company to determine whether you’re using the correct cable.  If you subscribe to video service over cable, the cable signal may not be reaching the modem. Confirm that good quality cable television pictures are available to the coaxial connector you are using by connecting a television to it. If your cable outlet is “dead”, call your Cable Company.
Chapter 3: Additional Information 68 Illustrations contained in this document are for representation only.  Verify that the Cable Modem service is DOCSIS-compliant and PacketCable-compliant by calling your cable provider. I don’t hear a dial tone when I use a telephone.  Telephone service is not activated. If the rightmost light on the Residential Voice Gateway stays on while others flash, check with your TSP or cable company.  If the Residential Voice Gateway is connected to existing house telephone wiring, make sure that another telephone service is not connected. The other service can normally be disconnected at the Network Interface Device located on the outside of the house.  If using the second line on a two-line telephone, be sure to connect to port TEL1/2.
