What Is the ProSafe Gigabit Quad WAN SSL VPN Firewall
SRX5308?
The ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308, hereafter referred to as the
VPN firewall, connects your local area network (LAN) to the Internet through up to four
external broadband access devices such as cable or DSL modems or satellite or wireless
Internet dishes. Four wide area network (WAN) ports allow you to increase effective data rate
to the Internet by utilizing all WAN ports to carry session traffic or to maintain backup
connections in case of failure of your primary Internet connection.
The VPN firewall routes both IPv4 and IPv6 traffic. A powerful, flexible firewall protects your
IPv4 and IPv6 networks from denial of service (DoS) attacks, unwanted traffic, and traffic
with objectionable content. IPv6 traffic is supported through 6to4 and Intra-Site Automatic
Tunnel Addressing Protocol (ISATAP) tunnels.
Introduction
12
ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
The VPN firewall is a security solution that protects your network from attacks and intrusions.

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 through
email. Network administrators can establish restricted access policies based on time of day,
website addresses, and address keywords.
The VPN firewall provides advanced IPSec and SSL VPN technologies for secure and simple
remote connections. The use of Gigabit Ethernet LAN and WAN ports ensures high data
transfer speeds.
The VPN firewall is a plug-and-play device that can be installed and configured within

connect additional broadband Internet lines that can be configured to:
• L
oad-balance outbound traffic between up to four lines for maximum bandwidth
efficiency.
• Pro
vide backup and rollover if one line is inoperable, ensuring that you are never

ix B, Network Planning for Multiple WAN Ports (IPv4 Only) for the planning
factors to consider when implementing the following capabilities with multiple WAN port
gateways:
• Single
or multiple exposed hosts.
• V
irtual private networks (VPNs).

A Powerful, True Firewall with Content Filtering
Unlike simple NAT routers, the VPN firewall is a true firewall, using stateful packet inspection
(SPI) to defend against hacker attacks. Its firewall features have the following capabilities:
• DoS protection.
Automatically detects and thwarts denial of service (DoS) attacks such
as Ping of Death and SYN flood.
• Secure firewall. Blocks un
wanted traffic from the Internet to your LAN.
• Content fil
tering. Prevents objectionable content from reaching your computers. You
can control access to Internet content by screening for web services, web addresses, and
keywords within web addresses.
• Schedul
e policies. Permits scheduling of firewall policies by day and time.
• Logs security incident
s. Logs security events such as logins and secure logins. You can
configure the 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
when a significant event occurs.
Security Features
The VPN firewall is equipped with several features designed to maintain security:
• Computers h
idden 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
computers on the LAN.
• Port forwarding
with NAT. Although NAT prevents Internet locations from directly
accessing the computers on the LAN, the VPN firewall allows you to direct incoming
traffic to specific computers based on the service port number of the incoming request.
• DMZ po
rt. Incoming traffic from the Internet is usually 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 use the
dedicated demilitarized zone (DMZ) port to forward the traffic to one computer on your
network.
Autosensing Ethernet Connections with Auto Uplink
With its internal four-port 10/100/1000 Mbps switch and four 10/100/1000 WAN ports, the
VPN firewall can connect to a 10-Mbps standard Ethernet network, a 100-Mbps Fast Ethernet
Introduction
15
ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
network, a 1000-Mbps Gigabit Ethernet network, or a combination of these networks. All LAN
and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation.
The VPN firewall incorporates Auto Uplink
TM
technology. Each Ethernet port automatically
senses whether the Ethernet cable plugged into the port should have a normal connection
such as to a computer or an uplink connection such as to a switch or hub. That port then
configures itself correctly. This feature eliminates the need for you to think about crossover
cables, as Auto Uplink accommodates either type of cable to make the right connection.
Extensive Protocol Support
The VPN firewall supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol (RIP). The VPN firewall provides the following protocol support:
• I
P address sharing by NAT. The VPN firewall allows many networked computers to
share an Internet account using only a single IP address, which might be statically or
dynamically assigned by your Internet service provider (ISP). This technique, known as
Network Address Translation (NAT), allows the use of an inexpensive single-user ISP
account.
• Automatic configuration of att
ached computers by DHCP. The VPN firewall
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 computers on your local network.
• DNS proxy. Whe
n DHCP is enabled and no DNS addresses are specified, the VPN
firewall provides its own address as a DNS server to the attached computers. The firewall
obtains actual DNS addresses from the ISP during connection setup and forwards DNS
requests from the LAN.
• PPP over Ethernet (PPP
oE). PPPoE is a protocol for connecting remote hosts to the
Internet over a DSL connection by simulating a dial-up connection.
• Qualit
y of Service (QoS). The VPN firewall supports QoS, including traffic prioritization
and traffic classification with Type of Service (ToS) and Differentiated Services Code
Point (DSCP) marking.
• L
ayer 2 Tunneling Protocol (L2TP). A tunneling protocol that is used to support virtual
private networks (VPNs).
• Poi
nt to Point Tunneling Protocol (PPTP). Another tunneling protocol that is used to
support VPNs.
Easy Installation and Management
You can install, configure, and operate the VPN firewall within minutes after connecting it to
the network. The following features simplify installation and management tasks:
• Browser-base
d management. Browser-based configuration allows you to easily
configure the VPN firewall from almost any type of operating system, such as Windows,
Macintosh, or Linux. Online help documentation is built into the browser-based web
management interface.
Introduction
16
ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
• Auto-detection of ISP. The VPN firewall automatically senses the type of Internet
connection, asking you only for the information required for your type of ISP account.
• IPSec VPN W
izard. The VPN firewall includes the NETGEAR IPSec VPN Wizard so you
can easily configure IPSec VPN tunnels according to the recommendations of the Virtual
Private Network Consortium (VPNC). This ensures that the IPSec VPN tunnels are
interoperable with other VPNC-compliant VPN routers and clients.
• SNMP. The
VPN firewall supports the Simple Network Management Protocol (SNMP) to
let you monitor and manage log resources from an SNMP-compliant system manager.
The SNMP system configuration lets you change the system variables for MIB2.
• Diagnosti
c functions. The VPN firewall incorporates built-in diagnostic functions such
as ping, traceroute, DNS lookup, and remote reboot.
• Remote m
anagement. The VPN firewall allows you to log in to the web management
interface from a remote location on the Internet. For security, you can limit remote
management access to a specified remote IP address or range of addresses.
• V
isual monitoring. The VPN firewall’s front panel LEDs provide an easy way to monitor
its status and activity.
Maintenance and Support
NETGEAR offers the following features to help you maximize your use of the VPN firewall:
• Flash memo
ry for firmware upgrades.
