Installing Your Gateway  
Finding a Suitable Location  
Your SMCD3GN Wireless Cable Modem Gateway can be installed in any location with  
access to the cable network. All of the cables connect to the rear panel of the Gateway for  
better organization and utility. The LED indicators on the front panel are easily visible to  
provide you with information about network activity and status.  
For optimum performance, the location you choose should:  
y
y
y
y
Be close to a working AC power outlet.  
Allow sufficient air flow around the Gateway to keep the device as cool as possible.  
Not expose the Gateway to a dusty or wet environment.  
Be an elevated location such as a high shelf, keeping the number of walls and ceilings  
between the Gateway and your other devices to a minimum.  
y
y
Be away from electrical devices that are potential sources of interference, such as ceiling  
fans, home security systems, microwaves, or the base for a cordless phone.  
Be away from any large metal surfaces, such as a solid metal door or aluminum studs.  
Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors,  
brick, and concrete can also affect your wireless signal.  
Connecting to the LAN  
Using an Ethernet LAN cable, you can connect the Gateway to a desktop computer,  
notebook, hub, or switch. Your Gateway supports auto-MDI/MDIX, so you can use either a  
standard straight-through or crossover Ethernet cable.  
1. Connect either end of an Ethernet cable to one of the four LAN ports on the rear panel of  
the Gateway (see Figure 3).  
Figure 3. Connecting to a LAN Port on the Gateway Rear Panel

Installing Your Gateway  
2. Connect the other end of the cable to your computer’s network-interface card (NIC) or to  
another network device (see Figure 4).  
Figure 4. Connecting the Gateway to the a Laptop or Desktop Computer  
Connecting the WAN  
To connect your Gateway to a Wide Area Network (WAN) interface:  
1. Connect a coaxial cable to the port labeled Cable on the rear panel of the Gateway from a  
cable port in your home or office (see Figure 2 on page 13). Use only manufactured coaxial  
patch cables with F-type connectors at both ends for all connections.  
2. Hand-tighten the connectors to secure the connection.  
3. If the modem was not installed by your cable provider (ISP) or is replacing another cable  
modem, contact your cable operator to register the SMCD3GN. If the modem is not  
registered with your cable operator, it will be unable to connect to the cable network  
system.  
Powering on the Gateway  
After making your LAN and WAN connections, use the following procedure to power on the  
Gateway:  
1. Connect the supplied power adapter to the port labeled 12VDC on the rear panel of the  
Gateway (see Figure 2 on page 13).  
2. Connect the other end of the power adapter to a working power outlet. The Gateway  
powers on automatically, the POWER LED on the front panel goes ON, and the other front  
panel LEDs show the Gateway’s status (see Table 1 on page 12).  
WARNING: Only use the power adapter supplied with the Gateway. Using a different power  
adapter can damage your Gateway and void the warranty.

Description  
Enable UPnP  
Configures your Gateway as a Universal Plug and Play (uPnP) Internet gateway. UPnP allows for dynamic  
connectivity between devices on a network. A UPnP-enabled device like your Gateway can obtain an IP address,  
advertise its capabilities, learn about other connected UPnP devices and then communicate directly with those  
devices. The same device can end its connection cleanly when it wishes to leave the UPnP community. The intent  
of UPnP is to support zero-configuration, "invisible" networking of devices including intelligent appliances, PCs,  
printers, and other smart devices using standard protocols.  
Check = uPnP is enabled on the Gateway. (default)  
Uncheck = uPnP is disabled on the Gateway.  
Enable HNAP  
Configures your Gateway as a Home Network Administration Protocol (HNAP) device. HNAP allows your  
Gateway to be configured and managed by remote entities, such as Network Magic or any software application  
that discovers and manages network devices.  
Check = HNAP is enabled on the Gateway.  
Uncheck = HNAP is disabled on the Gateway. (default)

created during the protocol communications. Normally, a normal treats the triggered  
sessions as independent sessions and blocks them. However, your Gateway can co-relate  
the triggered sessions with the initial session and group them together in the NAT session  
table. As a result, you need only specify which protocol type and port number you want to  
track, as well as some other related parameters. In this way, the Gateway can pass the  
special applications according to the supplied information.

Assume, for example, that to use H.323 in a Net Meeting application, a local client starts a  
session A to a remote host. The remote host uses session A to communicate with the local  
host, but it also could initiate another session B back to the local host. Since there is only  
session A recorded in the NAT session table when the local host starts the communication,  
session B is treated as an illegal access from the outside and is blocked. Using the Special  
Application menu, you can configure the Gateway to co-relate sessions A and B and  
automatically open the port for the incoming session B.

host's IP in the datagram and normal NAT would not translate the IP address in the datagram.  
To make sure the network address translation is complete, IP replacement is necessary for  
these special applications, such as H.323.  
Allow sessions initiated from/to the  
3rd host  
Decide whether the sessions can start from/to a third host. To prevent hacker attacks from a  
3rd host, this feature usually is not allowed. However, for some special applications, such as  
MGCP in a VOIP application, a session initiated from a third host is permitted. For example,  
assume Client A is trying to make a phone call to a host B. Client A tries to communicate with  
the Media Gateway Controller (MGC) first and provides host B's number to the MGC. Then  
MGC checks its own database to find B and communicate with B to provide B the information  
about A. B uses this information to communicate directly to A. So initially, A is talking to MGC,  
but the final step has B initiating a session to A. If the 3rd-host-initiated session is not allowed  
in this example, the whole communication fails.  
Configuring URL Blocking  
Using the URL Blocking menu, you can configure your Gateway to block access to certain  
Web sites from local computers by entering either a full URL address or keywords of the  
Web site. Your Gateway examines all the HTTP packets to block the access to those  
particular sites. This feature can be used to protect children from accessing inappropriate  
Web sites. You can block up to 50 sites.  
Using URL blocking, you can also make up to 10 computers exempt from URL blocking and  
have full access to all Web sites at any time.  
To display the URL Blocking menu, click Firewall in the menu bar and then click the URL  
Blocking submenu. Figure 31 shows an example of the menu.  
Note: The Gateway provides a Schedule Rules feature that lets you configure URL blocking  
for certain days, if desired. For more information, see “Configuring Schedule Rules” on page  
54.
