Using equipment safely
Your Cable Modem Gateway product has been manufactured to meet European and local safety standards,
but you must take care if you want it to perform properly and safely.
It is important that you read this booklet completely, especially the safety instructions below.
Equipment connected to the protective earth of the building installation through the mains connection or
through other equipment with a connection to protective earth and to a cable distribution system using
coaxial cable, may in some circumstances create fire hazard. Connection to a cable distribution system has
therefore to be provided through a device providing electrical isolation below a certain frequency range
(galvanic isolator, see EN 60728-11).
If you have any doubts about the installation, operation or safety of the product, please contact your supplier.
To avoid the risk of electric shock
Disconnect the Cable Modem Gateway product from the mains supply before you connect it to (or
disconnect it from) any other equipments. Remember that contact with Mains can be lethal or causes
severe electric shock.
Never remove the product cover. Should the product fail, contact the Customer Service to arrange
repair or service.
Never allow anyone to push anything into holes, slots or any other opening in the case
Do not block the ventilation slots; never stand it on soft furnishings or carpets
Do not put anything on it which might spill or drip into it (e.g. Lighted candles or containers of liquids).
Do not expose it to dripping or splashing. If an object or liquid enters inside the Cable Modem, unplug
it immediately and contact the Customer Service.
Do not store the Cable Modem Gateway product in excessively hot, cold or damp conditions. It is
intended to operate at an ambient temperature of less than 35 degrees Celsius and a maximum humidity
level of 70%. In case of a storm, it is recommended that you unplug the product from the mains and
from the PC set or other equipment.
Leave the mains socket accessible so that you can unplug the set quickly
Telephone jacks Line 1 and Line 2 must not be connected to outside wiring.
Connecting to the mains supply
This appliance is designed to operate in the rated voltage 110 ~ 240 VAC.
If you are in any doubt about the mains lead, the plug or connection, please consult the Customer
Service.
Only the power adapter supplied with the product has to be used.
Ensuring optimum performance
Leave 7cm to 10cm around the appliance to ensure that proper ventilation gets to it.
Do not store your appliance on its side (if not allowed)
To clean the appliance, use a dry, clean soft cloth with no cleaning solvent or abrasive products. Clean
the ventilation openings regularly.

    3. MAC Filtering This page enables you to enter the MAC address of specific PCs on your LAN that you do not wish to 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.
  • Page 41: Port Filtering

    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).
  • Page 42: Forwarding

    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.
  • Page 43 Press ‘Create Ipv4’ button to specify rules. Choose Service Name or Port number range to set up. IP Address 0.0.0.0 means allow all IP address. This will cause inbound packets that match to be forwarded to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the Connection Table.
  • Page 44: Port Triggers

    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.
  • Page 45 Press ‘Create’ button to specify rules. Choose Service Name or Port number range to set up. IP Address 0.0.0.0 means allow all IP address. This will cause inbound packets that match to be forwarded to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the Connection Table.
  • Page 46: Dmz Host

    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. e.g., 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.
  • Page 47: Rip Setup

    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.
