The Gateway’s Functions

Wireless-G ADSL Gateway with 2 Phone Ports

Chapter 1: Planning Your Network

The Gateway’s Functions

A Gateway is a network device that connects two networks.

This Gateway connects your local network, or the group of computers in your home or office, to the Internet. The

Gateway processes and regulates the data that travels between these two networks.

The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see”

your computers.

This is how your network remains private. The Gateway protects your network by inspecting

every packet coming in through the Internet port before delivery to the appropriate computer on your network.

The Gateway inspects Internet port services like the web server, ftp server, or other Internet applications, and, if

allowed, it will forward the packet to the appropriate computer on your network.

Remember that the Gateway’s ports connect to two sides. The network ports connect to your network, and the

ADSL port connects to the Internet.

The network ports transmit data at 10/100Mbps.

IP Addresses

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including computers, print servers, and

Gateways, requires an IP address to identify its “location,” or address, on the network.

This applies to both the

Internet and network connections. There are two ways of assigning an IP address to your network devices. You

can assign static IP addresses or use the Gateway to assign IP addresses dynamically.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a computer or other device on the network.

Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned

it will always have that same IP address until you change it.

Static IP addresses must be unique and are

commonly used with network devices such as server computers or print servers.

NOTE:

Since the Gateway is a device that connects

two networks, it needs two IP addresses—one for

your network, and one for the Internet.

In this User

Guide, you’ll see references to these address.”

Since the Gateway uses NAT technology, the only IP

address that can be seen from the Internet for your

network is the Gateway’s Internet IP address.

However, even this Internet IP address can be blocked,

so that the Gateway and network seem invisible to the

Internet—see the Block WAN Requests description

under Security in

Chapter 4: Configuring the Gateway
