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 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 address by various means, including a DHCP server, by you directly entering it, or sometimes by a PC generating one of its own. Ethernet requires that each TCP/IP stack on the Wireless Cable Gateway also have associated with it an Ethernet MAC (Media Access Control) address. MAC addresses are permanently fixed into network devices at the time of their manufacture. 00:90:64:12:B1:91 is an example of a MAC address.

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 MAC and IP Addresses Summary This table summarizes all the MAC and IP addresses that may be associated with the TCP/IP communication stacks and USB handling in your Wireless Cable Gateway. The ones actually used depend upon your gateway Operating Mode, as explained above. At minimum, your cable company will need to know the MAC address associated with IP Stack 1, which is the MAC address shown on the modem label.
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 Status Web Page Group Software Web Page (Fig. 17) 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 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 (Fig. 18) 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 Chapter 3 31 DCW725 book file.
Chapter 3: Advanced Configuration Password Web Page (Fig. 19) 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 Event Log Web Page (Fig. 20) This page provides diagnostic information regarding the cable modem section of your gateway that may be useful to your cable company if you are having startup or operation issues. As long as your gateway startup and operational performance is normal, any messages contained in this log can be ignored. Diagnostics Web Page (Fig.
Chapter 3: Advanced Configuration Network Web Page Group WAN Web Page (Fig. 22) 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 LAN and Computers Web Pages (Fig. 23 and 24) 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. With this function activated, your cable company’s DHCP server provides one IP address for your gateway, and your gateway’s DHCP server provides IP addresses, starting at the address you set in IP Address on the LAN page, to your PCs.
Chapter 3: Advanced Configuration Advanced Web Page Group Options Web Page (Fig. 25) 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 Check Multicast Enable and then click Apply to enable multicast traffic to pass WAN <=> LAN. You may need to enable this to see some types of broadcast streaming and content on the Internet, such as webcasting of a popular live event. IP Filtering Web Page (Fig. 26) This page enables you to enter the IP address ranges of PCs on your LAN that you don’t want to have outbound access to the WAN.
Chapter 3: Advanced Configuration Port Filtering Web Page (Fig. 28) 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 filtering, set Start Port and End Port for each range, and click Apply.
Chapter 3: Advanced Configuration Forwarding Web Page (Fig. 29) 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 (Fig. 30) 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 DMZ Host Web Page (Fig. 31) 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. 31 Chapter 3 41 DCW725 book file.
Chapter 3: Advanced Configuration Routing Information Protocol Setup Web Page (Fig. 32) 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 (Fig. 33 and 34) 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 Time of Day Access Filter Web Page (Fig. 35) 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. 35 44 DCW725 book file.
Chapter 3: Advanced Configuration Local Log and Remote Log Web Pages (Fig. 36 and 37) 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 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 DCW725 gateway offers a choice of 802.
Chapter 3: Advanced Configuration Privacy Privacy 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 privacy-related setting changes to factory defaults are recommended. See the 802.11b/g Privacy Web Page discussion below for details.
