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.

For example, the VPN firewall provides support for stateful packet inspection (SPI), 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 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

minutes.

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

See Append

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).

- Allows browser-based, platform-independent remote access through a number of

popular browsers, such as Microsoft Internet Explorer, Mozilla Firefox, and Apple

Safari.

- Provides granular access to

corporate resources based on user type or group

membership.

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.
