Static IP Address

When the Router is configured to use Static IP Address assignment for

the WAN connection, you must manually assign a global IP Address,

Subnet Mask, and Default Gateway IP address used for the WAN

connection.

To configure a Static IP Address WAN connection, follow these steps:

1. Change the IP Address, Subnet Mask, and Default Gateway as

instructed by your ISP. These are the global IP settings for the WAN

interface. This is the “visible” IP address of your account. Your ISP

should have provided these IP settings to you.

2. Choose the Connection Type from the drop-down menu. This

defines both the connection protocol and encapsulation method

used for your ADSL service. The available options are 1483

Bridged IP LLC, 1483 Bridged IP VC-Mux, 1483 Routed IP LLC,

and 1483 Routed IP VC-Mux. If you have not been provided

specific information for this setting, leave the default setting.

3. NAT should remain Enable. If you disable NAT, you will not be able

to use more than one computer for Internet connections. If you are

using multiple virtual connections, NAT functions system-wide,

therefore if it is disabled, NAT will be disabled on all connections.

4. IGMP is set to Disable by default. Select Enable to allow IGMP

packets to go through the WAN interface in both directions.

5. Leave the Default Route enabled if you want to use the Router as

the default route to the Internet for your LAN. Whenever a

computer on the LAN attempts to access the Internet, the Router

becomes the Internet gateway to the computer. If you have an

alternative route for Internet traffic you may disable this without

effecting the Router’s connection.
