Fig.3: Multiple-PC Connection Note: You may need to check with your service provider in order to connect multiple computers.
Chapter 1: Connections and Setup Telephone or Fax Connection When properly connected, most telephony devices can be used with the Residential Voice Gateway just as with conventional telephone service. To make a normal telephone call, pick up the handset; listen for a dial tone, then dial the desired number.
Chapter 1: Connections and Setup Activating the Residential Voice Gateway After installing the Residential Voice Gateway and turn it on for the first time (and each time the modem is reconnected to the power), it goes through several steps before it can be used. Each of these steps is represented by a different pattern of flashing lights on the front of the modem.

Fig. 12 Gateway\Status\Backup/Restore To backup the current configuration, click “Backup” and follow the prompts. To restore a previous configuration, click “Browser” and use the navigation window to locate the file. ( UsuallyGatewaySettings.bin, unless you rename it before saving.
Chapter 2: Web Configuration Gateway – Network Web Page Group 1. LAN You can activate the DHCP server function for the LAN on this page. 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 2: Web Configuration 2. WAN You can configure the optional internal DHCP server for the WAN on this page. Select different WAN Connection Type will lead to different contents. Take the WAN connection type-DHCP for example, you can release and renew the WAN lease by pressing the buttons. You can enter a spoofed MAC address that causes your gateway networking stack to use that MAC address when communicating instead of the usual WAN MAC address, e.g., if the MAC address is 00:11:e3:df:66:95, this spoofed MAC address could be 00:11:e3:df:66:97 or any desired MAC address.
Chapter 2: Web Configuration 3. Computers This page displays the status of the DHCP clients and current system time. You can cancel an IP address lease by selecting it in the DHCP Client Lease Info list and then clicking the Force Available button. If you do so, you may have to perform a DHCP Renew on that PC, so that it can obtain a new lease.
Chapter 2: Web Configuration 4. DDNS Dynamic DNS (DDNS) allows a dynamic IP address to be aliased to a static, pre-defined host name so that the host can be easily contacted by other hosts on the internet even if its IP address changes. The CMRG supports a dynamic CNS client compatible with the Dynamic DNS service (http://www.dyndns.com/).

With WAN Blocking enabled, your gateway will not respond to pings it receives, effectively “hiding”...
Chapter 2: Web Configuration 2. IP Filtering 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 (Internet). These PCs can still communicate with each other on your LAN, but traffic they originate to the WAN is blocked by the gateway.
Chapter 2: Web Configuration 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.
Chapter 2: Web Configuration 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).
Chapter 2: Web Configuration 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.
Chapter 2: Web Configuration 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.
Chapter 2: Web Configuration 7. 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.
Chapter 2: Web Configuration 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.
Chapter 2: Web Configuration Gateway – Firewall Web Page Group 1. Web Content Filtering 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.
Chapter 2: Web Configuration 2. TOD Access Filtering 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, and then use the tools to specify blocking time.
Chapter 2: Web Configuration 3. Local Log and Remote Log The gateway builds a log of firewall blocking actions that 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.
Chapter 2: Web Configuration Gateway – Parental Control Web Page Group Basic Setup This page allows 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.
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.

If you select WPS Method to PIN then It will ask for PIN while configuring the WiFi AP by showing a text box so, you need to enter that PIN to establish the connection.
Chapter 2: Web Configuration 3. Guest Networks If enabled by the service provider, there are 3 additional Wireless Guest Networks can be configured and activated. The default guest network screen looks as follow: Fig 41 Gateway\Wireless\Guest Network These networks are independent of each others. Each network is controlled and configured similar to the primary network (described is the previous section).
Chapter 2: Web Configuration 4. Access Control This page allows you to make access control to the AP or connected clients by offering the MAC Addresses of the clients. Fig. 43 Gateway\Wireless\Access Control Administration Web page Access: It Allow or Deny access to Administration Web Page from PC connected over WiFi.
