Chapter 2: Networking Chapter 2: Networking Communications Data communication involves the flow of packets of data from one device to another. These devices include personal computers, Ethernet and USB hubs, cable modems, digital routers and switches, and highly integrated devices that combine functions, like the Wireless Cable Gateway. The gateway integrates the functionality often found in two separate devices into one.
Chapter 2: Networking Fig.11 Example: The Wireless Cable Gateway offers a number of built-in web pages, which you can use to configure its networking side; when you communicate with the networking side, your communication is following this path. Each packet on the Internet addressed to a PC in your home travels from the Internet downstream on the cable company’s system to the WAN side of your Wireless Cable Gateway.
Chapter 2: Networking initialization configures the cable modem with a CM IP (Cable Modem Internet Protocol) address, as shown in Figure 3, so the cable company can communicate directly with the CM itself. Networking Section The Networking section of your gateway also uses TCP/IP (Transmission Control Protocol/ Internet Protocol) for the PCs you connected on the LAN side.
Chapter 2: Networking device. IRC used in an Internet instant messaging program, HTTP used by a web browser, and FTP used by a file transfer program are all examples of applications. Inside the packet, these applications are designated by their port number. Port 80, the standard HTTP port, is an example of a port number.
Chapter 2: Networking Fig. 13 CM (Cable Modem) Mode provides basic home networking. In this mode, two IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the cable modem section only. This stack receives its IP address from the cable company during CM initialization. It uses the MAC address printed on the label attached to the Wireless Cable gateway.
Chapter 2: Networking Note that in CM Mode, packets passing to the Internet to/from your PCs do not travel through any of the IP stacks; instead they are directly bridged between the WAN and LAN sides. Residential Gateway (RG) Mode Fig. 14 Fig. 15 Illustrations contained in this document are for representation only.
Chapter 2: Networking RG (Residential Gateway) Mode provides basic home networking plus NAT (Network Address Translation). In this mode, three IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only. This stack receives its IP address from the cable company during CM initialization. It uses the MAC address printed on the label attached to the Wireless Cable Gateway. • IP Stack 3 - for use by you to remotely (i.e.
Chapter 2: Networking CableHome (CH) Mode Fig. 16 CH (CableHome) Mode provides all the functionality of RG mode and adds the ability of the cable company to control the home networking configuration of your Wireless Cable Gateway for you, so you don’t need to perform the configuration yourself. In this mode, four IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only.
Chapter 2: Networking • IP Stack 4 - for use by you to remotely (i.e. from somewhere on the WAN side, such as at your remote workplace) communicate with the Cable Modem and Networking sections, to remotely access the internal web page diagnostics and configuration. This stack is also used by your cable company to deliver packets between the Internet and the Wireless Cable Gateway’s Networking section so they can be routed to/from your PCs.
Chapter 2: Networking USB-connected PC to make them look Ethernet-style when passed between you and your cable company. To do this, the gateway must effectively “loan” an Ethernet-style address for use in all these packets. For this purpose, the gateway uses a MAC address of MAC label + 5 (the MAC label is found on the bottom of the unit). E.g., if the MAC address is 00:90:64:12:B1:91, this MAC address would be 00: 90:64:12:B1:96.
Chapter 3: Advanced Configuration Chapter 3: Advanced Configuration Advanced User Configuration The Wireless Cable Gateway offers local management capability through a built in HTTP server and a number of diagnostic and configuration web pages. These pages are available from http://192.168.0.1 in RG and CH modes, and http://192.168.100.1 in CM Mode. Not all pages are available in some modes. Some information on two of the following web pages MUST BE configured, as explained in Mandatory User Configuration.
Chapter 3: Advanced Configuration Note: Your gateway complies with EURO-DOCSIS standards regarding software upgrades. EURO-DOCSIS requires that any software upgrade to a device that is connected to a cable system, like your gateway, must be "pushed" to the gateway by the cable operator. Also, the features of the gateway, and the embedded web pages that control those features, can vary by software version. Therefore, you may find that your gateway's web pages and features vary slightly from those shown here.
Chapter 3: Advanced Configuration Status Web Page Group Software Web Page The Information section of this page provides hardware and software information about your gateway that may be useful to your cable company. You can view your operating software version but not change it. This is because your gateway adheres to the EURO-DOCSIS Cable Modem standard, which requires that your cable company perform any software upgrade of the gateway from the gateway WAN side.
Chapter 3: Advanced Configuration Connection Web Page This page reports diagnostic information about the initialization and operating status of your gateway that can be useful at the time of installation. It can also be useful to your cable company’s support technician if you’re having problems. Fig.18 Illustrations contained in this document are for representation only.
Chapter 3: Advanced Configuration Password Web Page This page is used to set a password that enables you to access all the gateway internal web pages. The password can be a maximum of 8 characters and is case sensitive. In addition, this page can be used to restore the gateway to its original factory settings. Use this with caution, as all the settings you have made will be lost. To perform this reset, set Restore Factory Defaults to YES and click Apply.
Chapter 3: Advanced Configuration Diagnostics Web Page This page verifies you have IP connectivity from your gateway to other IP addresses on the LAN side, such as when you want to confirm you have successfully configured one of your PCs for TCP/IP operation. When you ping an Internet device, you send a packet to its TCP/IP stack, and it sends one back to yours. Enter the IP address you want to ping, then click Start Test. Wait a few seconds, then click your web browser’s refresh button.
Chapter 3: Advanced Configuration Network Web Page Group WAN Web Page This page gives you the ability to enter some data your cable company may require, as explained before in Mandatory User Configuration. In addition, it enables you to view your WAN side IP address and lease information. Your gateway can provide NAT/PAT (Network and Port Address Translation) as an element of security to prevent others from reaching your PCs when not authorized.
Chapter 3: Advanced Configuration explained in Chapter 2). Enter the desired MAC address and click Apply. Caution: If you enter a MAC address in use by another party, it can cause an address conflict on the network that could affect both you and that party. LAN and Computers Web Pages These pages give you the ability to activate and deactivate the DHCP server function of your gateway, and, if the DHCP server is activated, to see DHCP leases it has provided.
Chapter 3: Advanced Configuration Fig. 22 Fig.
Chapter 3: Advanced Configuration Advanced Web Page Group Options Web Page This page allows you to enable/disable some features of the Wireless Cable Gateway. Check WAN Blocking and then click Apply to prevent others on the WAN side from being able to ping your gateway. With WAN Blocking on, your gateway will not respond to pings it receives, effectively “hiding” your gateway. Check Ipsec Pass Through and then click Apply to enable IpSec type packets to pass WAN <=> LAN.
Chapter 3: Advanced Configuration This function works only if your gateway is in the RG mode. When accessing your gateway from a remote location, you must use HTTP port 8080 and your IP Stack 3 address. This is the "WAN IP address" that appears at the Network...WAN page. For example, if this IP address were 157.254.5.7, you would navigate to http://157.254.5.7:8080 to reach your gateway from a remote location. Check Multicast Enable and then click Apply to enable multicast traffic to pass WAN <=> LAN.
Chapter 3: Advanced Configuration MAC Filtering Web Page 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.26 Illustrations contained in this document are for representation only.
Chapter 3: Advanced Configuration Port Filtering Web Page This page enables 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 ltering, set Start Port and End Port for each range, and click Apply.
Chapter 3: Advanced Configuration Forwarding Web Page 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.
Chapter 3: Advanced Configuration Port Triggers Web Page 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 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.
Chapter 3: Advanced Configuration 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 6666 over TCP/IP. This destination port is within the Trigger Range, so the gateway automatically creates a forwarding rule to forward any inbound packets destined for port 113 to your game-playing PC at 192.168.0.10.
Chapter 3: Advanced Configuration DMZ Host Web Page 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.
Chapter 3: Advanced Configuration Routing Information Protocol Setup Web Page 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.
Chapter 3: Advanced Configuration Firewall Web Pages Group Web Content Filter and Parental Control Web Pages These pages allow you to enable, disable, and configure a variety of firewall features associated with web browsing, which uses the HTTP protocol and transports HTML web pages. On these pages, you designate the gateway packet types you want to have forwarded or blocked. You can activate settings by checking them and clicking Apply.
Chapter 3: Advanced Configuration Fig. 33 Illustrations contained in this document are for representation only.
Chapter 3: Advanced Configuration Time of Day Access Filter Web Page Use this page to set rules that will block specific LAN side PCs from accessing the Internet, but only at specific days and times. Specify a PC by its hardware MAC address, then use the tools to specify blocking time. Finally, click the Apply button to save your settings. Fig.
Chapter 3: Advanced Configuration Local Log and Remote Log Web Pages The gateway builds a log of firewall blocking actions that the Firewall has taken. Using the Local Log page lets you specify an email address to which you want the gateway to email this log. You must also tell the gateway your outgoing (i.e. SMTP) email server’s name, so it can direct the email to it. Enable Email Alerts has the gateway forward email notices when Firewall protection events occur.
Chapter 3: Advanced Configuration The Remote Log page allows you to specify the IP address where a SysLog server is located and select different types of firewall events that may occur. Then, each time such an event occurs, notification is automatically sent to this log server. Fig.
Chapter 3: Advanced Configuration Wireless Web Pages Group Important: Changes to the wireless web pages should be made from a PC that is hard wired 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 TCW710 gateway offers a choice of 802.
