IPsec (IP Security) is a security mechanism used in Virtual Private Networks (VPNs). PPTP PassThrough enables PPTP type packets to pass between WAN and LAN. PPTP (Point to Point Tunneling Protocol) is another mechanism sometimes used in VPNs. Remote Config Management makes the configuration web pages in your gateway accessible from the WAN side. Note that page access is limited to only those who know the gateway access password. When accessing your gateway from a remote location, your must use HTTP port 8080 and the WAN IP address of the gateway. e.g., if the WAN IP address is 157.254.5.7, you would navigate to http://157.254.5.7:8080 to reach your gateway. Multicast Enable enables multicast traffic to pass through WAN and LAN. You may need to enable this to see some types of broadcast streaming and content on the Internet. UPnP Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. NAT ALG enable NAT ALG (application layer gateways) allows customized NAT traversal filters to be plugged into the gateway to support address and port translation for certain application layer "control/data" protocols such as RSVP, FTP, TFTP, Kerb88, NetBios , IKE, RTSP, Kerb1293 , H225 , PPTP , MSN , SIP , ICQ , IRC666x , ICQTalk , Net2Phone , IRC7000 , IRC8000 file transfer in IM applications etc. In order for these protocols to work through NAT or a firewall, either the application has to know about an address/port number combination that allows incoming packets, or the NAT has to monitor the control traffic and open up port mappings (firewall pinhole) dynamically as required. Legitimate application data can thus be passed through the security checks of the firewall or NAT that would have otherwise restricted the traffic for not meeting its limited filter criteria. 22 Illustrations contained in this document are for representation only. ...

Page 28: Port Filtering
Chapter 3: Connections and setup 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 with the same value. Fig. 15: Port Filtering Settings 25 Illustrations contained in this document are for representation only. ... -
Page 29: Forwarding
Chapter 3: Connections and setup 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. Fig. 16: Forwarding Settings 26 Illustrations contained in this document are for representation only. ... -
Page 30: Port Triggers
Chapter 3: Connections and setup 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.

Chapter 4: Additional Information Chapter 4: Additional Information General Troubleshooting You can correct most problems you have with your product by consulting the troubleshooting list that follows. I cannot access the Internet. Check all of the connections to your EMTA. Your Ethernet card may not be working well. Check the documentation for more information. The Network Properties of your operating system may not be setting correctly. Check with your ISP or cable company. All of the lights are flashing in sequence. This means the EMTA 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 EMTA 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 (CABLE LINK light not on continuously). 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. The modem should work with a standard RG‐6 coaxial cable, but if you’re using a cable other than 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. Verify that the EMTA service is DOCSIS 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 EMTA stays on while others flash, check with your TSP or cable company. 49 Illustrations contained in this document are for representation only. ... - Page 53 Chapter 4: Additional Information If the EMTA 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, use a 2‐line to 1‐line adapter cable. 50 Illustrations contained in this document are for representation only. ...

Page 55: Glossary
Chapter 4: Additional Information Glossary 10BaseT – Unshielded, twisted pair cable with an RJ‐45 connector, used with Ethernet LAN (Local Area Network). "10" indicates speed (10 Mbps), "Base" refers to baseband technology, and "T" means twisted pair cable. Authentication ‐ The process of verifying the identity of an entity on a network. DHCP (Dynamic Host Control Protocol) – A protocol with which allows a server to assign IP addresses dynamically to hosts on the fly. DOCSIS (Data Over Cable Service Interface Specifications) – A project with the objective of developing a set of necessary specifications and operations support interface specifications for cable modems and associated equipment. Ethernet card – A plug‐in circuit board installed in an expansion slot of a personal computer. The Ethernet card (sometimes called a Network Interface Card or NIC) takes parallel data from the computer, converts it to serial data, puts it into a packet format, and sends it over the 10BaseT or 100BaseT LAN cable. F Connector – A type of coaxial connector, labeled CABLE IN on the rear of the cable modem that connects the modem to the cable system. HTTP (HyperText Transfer Protocol) – Invisible to the user, HTTP is used by servers and clients to communicate and display information on a web browser. Hub – A device used to connect multiple computers to the cable modem. IP Address – A unique, 32‐bit address assigned to every device in a network. An IP (Internet Protocol) address has two parts: a network address and a host address. This modem receives a new IP address from your cable operator via DHCP each time it goes through Initialization Mode. Key exchange ‐ The swapping of mathematical values between entities on a network in order to allow encrypted communication between them. MAC Address – The permanent "identity" for a device programmed into the Media Access Control layer in the network architecture during the modem’s manufacturing. NID ‐ Network Interface Device, the interconnection between the internal house telephone wiring and a conventional telephone service provider’s equipment. These wiring connections are normally housed in a small plastic box located on an outer wall of the house. It is the legal demarcation between the subscriber’s property and the service provider’s property.
