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 modems or DSL modems. 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 is a complete 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 via 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

extremely 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:

• Load-balance between up to four lines for maximum bandwidth efficiency.

• Provide backup and rollover if one line is inoperable, ensuring that you are never

disconnected.

See Network Planning for Multiple WAN Ports on page 306 for the planning factors to

consider when implementing the following capabilities with multiple WAN port gateways:

• Single or multiple exposed hosts.

• Virtual private networks (VPNs).

Introduction

11

ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308

Advanced VPN Support for Both IPSec and SSL

The VPN firewall supports IPSec and SSL 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 125 concurrent IPSec VPN tunnels.

• SSL VPN provides remote access for mobile users to selected corporate resources

without requiring a pre-installed VPN client on their computers.

- Uses the familiar Secure Sockets Layer (SSL) protocol, commonly used for

e-commerce transactions, to provide client-free access with customizable user

portals and support for a wide variety of user repositories.

- 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.

- Supports 50 concurrent SSL VPN sessions.

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 unwanted traffic from the Internet to your LAN.

• Content filtering. Prevents objectionable content from reaching your PCs. You can

control access to Internet content by screening for web services, web addresses, and

keywords within web addresses. You can configure the VPN firewall to log and report

attempts to access objectionable Internet sites.

• Schedule policies. Permits scheduling of firewall policies by day and time.

• Logs security incidents. Logs 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 when a significant event

occurs.

Introduction

12

ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308

Security Features

The VPN firewall is equipped with several features designed to maintain security:

• 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 computers 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 use the

dedicated demilitarized zone (DMZ) port to forward the traffic to one PC 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 either a 10 Mbps standard Ethernet network, a 100 Mbps Fast

Ethernet network, or a 1000 Mbps Gigabit Ethernet network. The four LAN and four 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 PC 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). For further information about TCP/IP, see Internet

Configuration Requirements on page 308. The VPN firewall provides the following protocol

support:

• IP address sharing by NAT. The VPN firewall allows many networked PCs 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 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.

Introduction

13

ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308

• 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.

• Quality 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.

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-based 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.

• 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 Wizard. 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) to ensure 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.

• Diagnostic functions. The VPN firewalll incorporates built-in diagnostic functions such

as ping, traceroute, DNS lookup, and remote reboot.

• Remote management. 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.

• Visual 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 memory for firmware upgrades.

• Technical support seven days a week, 24 hours a day, according to the terms that are

Internet and WAN Configuration Tasks

Typically, the VPN firewall is installed as a network gateway to function as a combined LAN

switch and firewall in order to protect the network from incoming threats and provide secure

connections. To complement the firewall protection, NETGEAR advises that you use a

gateway security appliance such as a NETGEAR ProSecure STM appliance.

 Generally, seven steps are required to complete the 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 Quad WAN SSL VPN Firewall SRX5308 Installation Guide for complete steps. A

PDF of the Installation Guide is on the NETGEAR website at

http://support.netgear.com/app/products/model/a_id/13568.

2. Log in to the VPN firewall. After logging in, you are ready to set up and configure your

VPN firewall. See Log In to the VPN Firewall on page 20.

3. Configure the Internet connections to your ISPs. During this phase, you connect to your

ISPs. You can also program the WAN traffic meters at this time if desired. See Configure the

Internet Connections on page 24.

4. Configure the WAN mode. Select either NAT or classical routing. Select load balancing

mode, auto-rollover mode, or primary (single) WAN mode. For load balancing, you can also

select any necessary protocol bindings. See Configure the WAN Mode on page 32.

5. Configure secondary WAN addresses on the WAN ports (optional). Configure aliases

for each WAN port. See Configure Secondary WAN Addresses on page 41.

6. Configure dynamic DNS on the WAN ports (optional). Configure your fully qualified

domain names. See Configure Dynamic DNS on page 42.

7. Configure the WAN options (optional). You can enable each WAN port to respond to a

ping, and you can change the factory default MTU size and port speed. However, these are

advanced features and changing them is not usually required. See Configure Advanced

WAN Options on page 51.

Each of these tasks is detailed separately in this chapter.

Note: For information about how to configure the WAN meters, see Enable

the WAN Traffic Meter on page 263.

The configuration of LAN, firewall, scanning, VPN, management, and monitoring features is

described in later chapters.

Qualified Web Browsers

To configure the VPN firewall, you need to use a web browser such as Microsoft Internet

Explorer 6 or later, Mozilla Firefox 3 or later, or Apple Safari 3 or later with JavaScript,

cookies, and SSL enabled.

Although these web browsers are qualified for use with the VPN firewall’s web management

interface, SSL VPN users should choose a browser that supports JavaScript, Java, cookies,

SSL, and ActiveX to take advantage of the full suite of applications. Note that Java is required

only for the SSL VPN portal, not for the web management interface.

Log In to the VPN Firewall
