Chapter 2: Connections and Setup Mandatory User Configuration This feature allows you to configure the gateway to function in your network and gain access to the Internet through your cable company. Your ISP may require the use of a Host Name and Domain Name. You will need to get the setup information from your ISP. If you do not have this information, please contact your ISP before proceeding. The instructions from your ISP will tell you how to set up your PC for Internet access.
Chapter 2: Connections and Setup Static IP Address and IP Mask: If your cable company says that you are connected through a static or fixed IP address, you should enter the field of Default Gateway, Primary DNS and/or Secondary DNS also. Spoofed MAC Address: You can give a spoofed MAC Address to hide your gateway’s real MAC address. However, this is NOT recommended, as this could cause an address conflict, causing your connection to the network to be rejected. 4.
Chapter 3: Networking and Advanced Settings Advanced User Configuration Three Networking Modes Your gateway can be configured to provide connectivity between your cable company and your home LAN in any one of three Networking Modes: CM, RG, and CH. This mode setting is under the control of your cable company, who can select the mode to match the level of home networking support for which you have subscribed.
Chapter 3: Networking and Advanced Settings Status Web Page Group Software Web Page (Fig. 12) Fig. 12 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: Networking and Advanced Settings Security Web Page (Fig. 14) Fig. 14 This page is used to set a password that enables you to access all the internal web pages as explained before under Mandatory User Configuration. 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.
Chapter 3: Networking and Advanced Settings Basic Web Page Group Setup Web Page (Fig. 16) 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 change your default LAN side IP address from 192.168.0.1, and to view your WAN side IP address and lease information. Fig.
Chapter 3: Networking and Advanced Settings DHCP Web Page (Fig. 17) This page gives 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 Fig. 17 DHCP server provides IP addresses, starting at the address you set in Starting Local Address, to your PCs.
Chapter 3: Networking and Advanced Settings Advanced Web Page Group Options Web Page (Fig. 18) This page allows you to enable/disable some features of the Wireless Cable Gateway. Check WAN Blocking and then 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. Fig. 18 Check Ipsec Pass Through and then Apply to enable IpSec type packets to pass WAN <=> LAN.
Chapter 3: Networking and Advanced Settings IP Filtering Web Page (Fig. 19) 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. These PCs can still communicate with each other on your LAN, but packets they originate to WAN addresses are blocked by the gateway. Fig. 19 MAC Filtering Web Page (Fig. 20) 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.
Chapter 3: Networking and Advanced Settings Forwarding Web Page (Fig. 22) Fig. 22 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.
Chapter 3: Networking and Advanced Settings 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 (see Advanced...Forwarding discussion above). This rule is valid until 10 minutes after it sees game activity stop.
Chapter 3: Networking and Advanced Settings Firewall Web Pages Group Time of Day (Fig 26) The Firewall ToD filter page allows you to control the internet access time period for a specific PC. This is a very useful Parental Control Feature on top of Content Filtering and Domain Blocking. It allows you to restrict the Internet access of some PCs to a limited period of time. Fig.
Chapter 3: Networking and Advanced Settings Event Log Web Page (Fig. 28) Fig. 28 The gateway builds a log of firewall blocking actions that the Firewall has taken. Using this 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: Networking and Advanced Settings Wireless Web Pages Group Enable Web Page (Fig. 30) Use this page to enable or disable the wireless functionality. If you enable it for the first time, proceed then to the “Basic” Web Page to configure the wireless settiings. Fig. 30 Basic Web Page (Fig. 31) Use this page to configure the wireless channel you want to use and the name you will assign to your network (SSID).
Chapter 3: Networking and Advanced Settings type a word or sentence and click on “generate WEP keys.” The gateway will automatically generate a key randomly. You have to write it down and use the same on the wireless equipped PC to allow proper descrambling. Advanced Web Page (Fig. 33) This page enables some advanced 802.11b settings to be made. The factory default values should provide good results in most cases. We don’t recommend you change these settings unless you have technical knowledge of 802.
Chapter 3: Networking and Advanced Settings authentication, and the access point (AP) responds with a WEP-encrypted challenge. The station can decrypt the challenge and respond only if it has the correct WEP password. When both “Open system and Shared key” options are selected, the authentication will be done according to the mobile client station) request : with or without encryption?? In both of these methods, the station must also know the service set identifier (SSID) of the Access Point.
Chapter 3: Networking and Advanced Settings Determining WiFi MAC Address (Fig. 35) If a printed WiFi MAC address for a PC cannot be found, it can be determined as follows from the MS-DOS prompt in the MS Windows running on that computer: 1. Start MS-DOS. In Windows 98, this is “Start” ... “Run” ,,, [type in] “command” ... “OK”. In Windows Me, 2k and XP, this is “Start” ... “Run” ... [type in] “cmd” ... OK. 2. List your installed interfaces, by typing “ipconfig /all” and pressing “Enter.” Fig. 35 3.
