Chapter 1: Planning Your Network

The Gateway’s Functions

Wireless-G ADSL Gateway with 2 Phone Ports

Chapter1:PlanningYourNetwork

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 networkof 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,eventhis Internet IP addresscan beblocked,

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.

Chapter 1: Planning Your Network

What is a VPN?

Wireless-G ADSL Gateway with 2 Phone Ports

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have

assigned a static IP address to your account. If so, you will need that static IP address when configuring the

Gateway. You can get that information from your ISP.

Dynamic IP Addresses

Adynamic IPaddressis automatically assigned to adevice on the network, suchas computers and print servers.

These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device.

After a certain time period, they expire andmay change. If a computer logs onto the network (or the Internet) and

its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP

server. Thecomputer ornetworking device obtaining anIP addressis calledthe DHCPclient. DHCPfrees you from

having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the

Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you

run more than one DHCP server on your network, you will experience network errors, such as conflicting IP

addresses. To disable DHCP on the Gateway, see the DHCP section in Chapter 4: Configuring the Gateway.

What is a VPN?

A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Gateway, for instance - in

different networks that allows private data to be sent securelybetween networks. This establishes a private

network that can send data securely between these two locations or networks.

This is done by creating a “tunnel”. AVPN tunnel connects the two computers or networks and allows data to be

transmitted over the Internet as if it were still within those networks. While not a literal tunnel, this is a

connection secured by encrypting the data sent between the two networks.

VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network.

Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates

a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual

Private Networking can be used to create secure networks linking a central office with branch offices,

telecommuters, and/or professionals on the road (travelers can connect to a VPN Gateway using any computer

with VPN client software that supports IPSec, such as SSH Sentinel.)
