 IP Address Masquerading By Dynamic NAT+
The WER-401 wireless SOHO Firewall gateway allows several networked computers to share an
Internet account using only a single IP address, which may be statically or dynamically assigned by
your Internet service provider (ISP). This technique, an extension of Network Address Translation
(NAT), is also known as IP address masquerading and allows the use of an inexpensive single-user
ISP account.
 Automatic Configuration Of Attached Computers By DHCP
The WER-401 wireless SOHO Firewall gateway dynamically assigns network configuration
information, including IP, gateway, and domain name server (DNS) addresses, to attached computers
on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies
configuration of LAN-attached computers.
 DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the wireless SOHO Firewall gateway
provides its own address as a DNS server to the attached computers. The wireless SOHO Firewall
gateway obtains actual DNS addresses from the ISP during connection setup and forwards DNS
requests from the LAN.
 PPP Over Ethernet (PPPoE) And PPTP
PPP over Ethernet and PPTP are protocols for connecting remote hosts to the Internet over an
always-on connection by simulating a dial-up connection.
1.3.9 Easy Installation and Management

Chapter 3
Preparing Your Network
3.1 Introduction
This chapter describes how to prepare your computer network to connect to the Internet through the WER-
401 wireless SOHO Firewall gateway and how to order broadband Internet service from an Internet service
provider (ISP).
3.2 Preparing Your Personal Computers for IP Networking
The WER-401 wireless SOHO Firewall gateway uses the Transmission Control Protocol/Internet Protocol
(TCP/IP). In order to access the Internet through the wireless SOHO Firewall gateway, each computer on
your network must have TCP/IP installed and selected as the networking protocol.
Most operating systems include the software components you need to install and use TCP/IP on your
computer:
 Windows 95 or later (including Windows NT) includes the software components for establishing a
TCP/IP network.
 Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/IP
application.
 Macintosh Operating System 7 or later includes the software components for establishing a
TCP/IP network.
 All versions of UNIX or Linux include TCP/IP components.
Follow the instructions provided with your operating system or networking software to install TCP/IP on
your computer. Although TCP/IP is built into the Windows operating system (starting with Windows 95),
you need to enable and configure it (see later).
In your IP network, all computers and the wireless SOHO Firewall gateway must be assigned IP addresses.
Each computer must also have certain other IP configuration information such as a subnet mask (netmask),
