v1.1, August 2010
Chapter 1
Introduction
The ProSafe Gigabit 8 Port VPN Firewall FVS318G with eight 10/100/1000 Mbps Gigabit
Ethernet LAN ports and one 10/100/1000 Mbps Gigabit Ethernet WAN port connects your local
area network (LAN) to the Internet through an external access device such as a cable modem or
DSL modem.
The FVS318G is a complete security solution that protects your network from attacks and
intrusions. For example, the FVX538 provides support for Stateful Packet Inspection, Denial of
Service (DoS) attack protection and multi-NAT support. The VPN firewall supports multiple Web
content filtering options, plus browsing activity reporting and instant alerts—both via email.
Network administrators can establish restricted access policies based on time-of-day, website
addresses and address keywords.
The FVS318G is a plug-and-play device that can be installed and configured within minutes.
This chapter contains the following sections:
• “Key Features” on this page
• “Package Contents” on page 1-5
• “VPN Firewall Front and Rear Panels” on page 1-6
• “Default IP Address, Login Name, and Password” on page 1-8
• “Qualified Web Browsers” on page 1-8
Key Features
The FVS318G provides the following features:
• One 10/100/1000 Mbps Ethernet WAN port for connection to a WAN device, such as a cable
modem or DSL modem.
• Built-in eight-port 10/100/1000 Mbps Gigabit Ethernet LAN switch for extremely fast data
transfer between local network resources.
• Support for up to 253 internal LAN users.
• Advanced VPN support for IPsec.
1-1
v1.1, August 2010
ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual
• SNMP Manageable, optimized for the NETGEAR ProSafe Network Management Software
(NMS100).
• Easy, Web-based setup for installation and management.
• Advanced SPI Firewall and Multi-NAT support.
• Extensive Protocol Support.
• Login capability.
• One console port for local management.
• Front panel LEDs for easy monitoring of status and activity.
• Flash memory for firmware upgrade.
Advanced VPN Support for IPsec
The VPN firewall supports IPsec virtual private network (VPN) connections.
IPsec VPN delivers full network access between a central office and branch offices, or between a
central office and telecommuters. Remote access by telecommuters requires the installation of
VPN client software on the remote computer.
• IPsec VPN with broad protocol support for secure connection to other IPsec gateways and
clients.
• Bundled with a single-user license of the NETGEAR ProSafe VPN Client software (VPN01L)
• Supports 5 concurrent IPsec VPN tunnels.
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the FVS318G is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• DoS protection. Automatically detects and thwarts DoS attacks such as Ping of Death, SYN
Flood, LAND Attack, and IP Spoofing.
• Secure Firewall. Blocks unwanted traffic from the Internet to your LAN.
• Block Sites. Blocks access from your LAN to Internet locations or services that you specify as
off-limits.
• Logs security incidents. The FVS318G will log security events such as blocked incoming
traffic, port scans, attacks, and administrator logins. You can configure the VPN firewall to
email the log to you at specified intervals. You can also configure the VPN firewall to send
immediate alert messages to your email address or email pager whenever a significant event
occurs.
1-2 Introduction
v1.1, August 2010
ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual
• Keyword Filtering. With its URL keyword filtering feature, the FVS318G prevents
objectionable content from reaching your PCs. The VPN firewall allows you to control access
to Internet content by screening for keywords within Web addresses. You can configure the
VPN firewall to log and report attempts to access objectionable Internet sites.
Security Features
The FVS318G is equipped with several features designed to maintain security, as described in this
section.
• PCs Hidden by NAT. NAT opens a temporary path to the Internet for requests originating
from the local network. Requests originating from outside the LAN are discarded, preventing
users outside the LAN from finding and directly accessing the PCs on the LAN.
• Port Forwarding with NAT. Although NAT prevents Internet locations from directly
accessing the PCs on the LAN, the VPN firewall allows you to direct incoming traffic to
specific PCs based on the service port number of the incoming request. You can specify
forwarding of single ports or ranges of ports.
• DMZ port. Incoming traffic from the Internet is normally discarded by the VPN firewall
unless the traffic is a response to one of your local computers or a service for which you have
configured an inbound rule. Instead of discarding this traffic, you can have it forwarded to one
computer on your network.
Autosensing Ethernet Connections with Auto Uplink
With its internal 8-port 10/100/1000 Mbps switch and 10/100/1000 WAN port, the FVS318G can
connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or a
1000 Mbps Gigabit Ethernet network. The LAN and WAN interfaces are autosensing and capable
of full-duplex or half-duplex operation.
The VPN firewall incorporates Auto Uplink
sense whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as
to a PC or an “uplink” connection such as to a switch or hub. That port will then configure itself to
the correct configuration. This feature also eliminates the need to worry about crossover cables, as
Auto Uplink will accommodate either type of cable to make the right connection.

Extensive Protocol Support
The FVS318G supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protoco
Networking Basics” document that you can access from the link in “Related Documents” in
Appendix C.
• IP Address Sharing by NAT. The VPN firewall allows several networked PCs 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, known as NAT, allows the
use of an inexpensive single-user ISP account.
• Automatic Configuration of Attached PCs by DHCP. The VPN firewall dynamically
assigns network configuration information, including IP, gateway, and domain name server
(DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol
(DHCP). This feature greatly simplifies configuration of PCs on your local network.
• DNS Proxy. When DHCP is enabled and no DNS addresses are specified, the VPN firewall
provides its own address as a DNS server to the attached PCs. The VPN firewall obtains actual
DNS addresses from the ISP during connection setup and forwards DNS requests from the
LAN.
• PPP over Ethernet (PPPoE). PPPoE is a protocol for connecting remote hosts to the Internet
over a DSL connection by simulating a dial-up connection. This feature eliminates the need to
run a login program such as EnterNet or WinPOET on your PC.
l (RIP). For further information about TCP/IP, see the “TCP/IP
• Quality of Service (QoS). QoS support for traffic prioritization.
Easy Installation and Management
You can install, configure, and operate the FVS318G within minutes after connecting it to the
network. The following features simplify installation and management tasks:
• Browser-Based Management. Browser-based configuration allows you to easily configure
your VPN firewall from almost any type of personal computer, such as Windows, Macintosh,
or Linux. A user-friendly Setup Wizard is provided and online help documentation is built into

Chapter 2
Connecting the VPN Firewall to the Internet
This section provides instructions for connecting the ProSafe Gigabit 8 Port VPN Firewall
FVS318G, including these topics:
• “Understanding the Connection Steps” on this page
• “Logging into the VPN Firewall” on page 2-2
• “Navigating the Menus” on page 2-3
• “Configuring the Internet Connection to Your ISP” on page 2-4
• “Configuring the WAN Mode” on page 2-9
• “Configuring Dynamic DNS” on page 2-11
• “Configuring the Advanced Broadband Options” on page 2-13
Setting up VPN tunnels is covered in Chapter 5, “Virtual Private Networking.”
Understanding the Connection Steps
Typically, six steps are required to complete the basic Internet connection of your VPN firewall.
1. Connect the VPN firewall physically to your network. Connect the cables and restart your
network according to the instructions in the installation guide. See the ProSafe Gigabit 8 Port
VPN Firewall FVS318G Installation Guide for complete steps. A PDF of the Installation
Guide is on the NETGEAR website at: http://kbserver.netgear.com.
2. Log in to the VPN Firewall. After logging in, you are ready to set up and configure your
VPN firewall. You can also change your password and enable remote management at this
time. See “Logging into the VPN Firewall” on page 2-2.
3. Configure the Internet connection to your ISP. During this phase, you will connect to your
ISP. See “Configuring the Internet Connection to Your ISP” on page 2-4.
4. Configure the WAN mode. Select either NAT or classical routing. See “Configuring the
WAN Mode” on page 2-9.
5. Configure dynamic DNS on the WAN port (optional). As an option, configure your fully
qualified domain names during this phase. See “Configuring Dynamic DNS” on page 2-11.

ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual
6. Configure the WAN options (optional). As an option, change the VPN firewall’s Media
Access Control (MAC) address, the factory default MTU size, and the port speed. However,
these are advanced features and changing them is not usually required. See “Configuring the
Advanced Broadband Options” on page 2-13.
Each of these tasks is detailed separately in this chapter. The configuration of firewall and VPN
features is described in later chapters.
Note: In this manual, “WAN port” and “broadband port” both indicate the same port
through which the VPN firewall connects to the Internet.
Logging into the VPN Firewall
To connect to the VPN firewall, your computer needs to be configured to obtain an IP address
automatically via DHCP. If you need instructions on how to configure you computer for DHCP,
refer to the “Preparing Your Network” document that you can access from the link in Appendix C,
“Related Documents.”
To log in to the VPN firewall:
1. Connect to the VPN firewall by typing http://192.168.1.1 in the address field of your browser.
Figure 2-1
2. When prompted, enter admin for the VPN firewall user name and password for the VPN
firewall password, both in lower case letters. (The VPN firewall user name and password are
not the same as any user name or password you may use to log in to your Internet connection.)

3. Click Login. The Router Status screen displays. For more information about this screen, see
“Viewing the VPN Firewall Configuration and System Status” on page 6-30.
Note: You might want to enable remote management at this time so that you can log
in remotely in the future to manage the VPN firewall (see “Configuring an
External Server for Authentication” on page 6-11). If you enable remote
management, NETGEAR strongly advises you to change your password (see
“Changing Passwords and Settings” on page 6-8).
Navigating the Menus
The Web Configuration Manager menus are organized in a layered structure of main categories
and submenus:
• Main menu. The horizontal orange bar near the top of the page is the main menu, containing
the primary configuration categories. Clicking on a primary category changes the contents of
the submenu bar.
• Submenu. The horizontal grey bar immediately below the main menu is the submenu,
containing subcategories of the currently selected primary category.
• Tab. Immediately below the submenu bar, at the top of the menu active window, are one or
more tabs, further subdividing the currently selected subcategory if necessary.
• Option arrow. To the right of the tabs on some menus are one or more blue dots with an arrow
in the center. Clicking an option arrow brings up either a popup window or an advanced option
menu.
Tip: In the instructions in this manual, we may refer to a menu using the notation
primary | subcategory, such as Network Configuration | WAN Settings. In this
example, Network is the selected primary category (in the main menu) and
WAN Settings is the selected subcategory (in the submenu).
You can now proceed to the first configuration task, configuring the VPN firewall’s Internet
connection.

The Connection Status window should show a valid IP address and gateway. If the
configuration was not successful, skip ahead to “Manually Configuring Your Internet
Connection following this section, or see “Troubleshooting the ISP Connection” on page 7-4.
Note: If the configuration process was successful, you are connected to the Internet
through the WAN port.
If your WAN ISP configuration was successful, you can skip ahead to “Manually Configuring
Your Internet Connection” on page 2-6.
Manually Configuring Your Internet Connection
If you know your ISP connection type, you can bypass the Auto Detect feature and connect your
VPN firewall manually. Ensure that you have all of the relevant connection information such as IP
addresses, account information, type of ISP connection, and so on, before you begin. Unless your
ISP automatically assigns your configuration automatically via DHCP, you will need these
configuration settings from your ISP.
To manually configure your broadband ISP settings:
1. Select Network Configuration from the main menu and Broadband ISP Settings from the
submenu. The Broadband ISP Settings screen displays (see Figure 2-2 on page 2-4 for the
entire screen).
2. In the ISP Login section, choose one of these options:
• If your ISP requires an initial login to establish an Internet connection, click Yes (this is
the default).
• If a login is not required, click No and ignore the Login and Password fields.
Figure 2-4
3. If you clicked Yes, enter the ISP-provided Login and Password information.
