ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual

Chapter 1

Introduction

The SRXN3205 ProSafe Wireless-N VPN Firewall connects your wired local area network (LAN)
and your wireless LAN clients to the Internet (Wide Area Network) through an external broadband
access device such as a cable modem or DSL modem. As a complete security solution, the
SRXN3205 incorporates a powerful and flexible firewall to safeguard your networks, while
providing advanced IPsec and SSL VPN technologies for secure wired and wireless connections.

The ProSafe Wireless-N VPN Firewall is the basic building block of a wireless LAN
infrastructure. It provides connectivity between Ethernet wired networks and radio-equipped
wireless notebook systems, desktop systems, print servers, and other devices.

The SRXN3205 provides wireless connectivity to multiple wireless network devices within a fixed
range or area of coverage—interacting with a wireless network interface card (NIC) via an
antenna. Typically, an individual in-building access point provides a maximum connectivity area
of about a 500 foot radius. Consequently, the ProSafe Wireless-N VPN Firewall can support a
small group of users in a range of several hundred feet. Most access points can handle between 10
to 30 users simultaneously.

The ProSafe Wireless-N VPN Firewall acts as a bridge between the wired LAN and wireless
clients. Connecting multiple VPN firewalls via a wired Ethernet backbone can further lengthen the
wireless network coverage. As a mobile computing device moves out of the range of one access
point, it moves into the range of another. As a result, wireless clients can freely roam from one
Access Point to another and still maintain seamless connection to the network.

The auto-sensing capability of the ProSafe Wireless-N VPN Firewall allows packet transmission at
up to 300 Mbps, or at reduced speeds to compensate for distance or electromagnetic interference.

The Gigabit Ethernet LAN ports and WAN port ensure extremely high data transfer speeds.
The SRXN3205 is a plug-and-play device that can be installed and configured within minutes.
This chapter contains the following sections:

• “Key Firewall Features”

• “Wireless Networking Features”

• “Maintenance and Support”

• “Package Contents”

• “Front Panel Features”

• “Rear Panel Features”

• “Default IP Address, Login Name, and Password Location”

• “Qualified Web Browsers”

Key Firewall Features

The VPN firewall portion provides the following key features:

• A single 10/100/1000 Mbps Gigabit Ethernet WAN port for your Internet connection.

• Built-in four-port 10/100/1000 Mbps Gigabit Ethernet LAN switch for extremely fast data
transfer between local network resources and all of the wireless clients.

• Advanced IPsec and SSL VPN support

• Advanced stateful packet inspection (SPI) firewall with multi-NAT support

• Easy, web-based setup for installation and management

• Front panel LEDs for easy monitoring of status and activity

• Flash memory for firmware upgrade

• AC-DC power adapter for low current draw

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the SRXN3205 is a true firewall, using stateful packet
inspection (SPI) to defend against hacker attacks. Its firewall features include:

• Automatically detects and thwarts denial of service (DoS) attacks such as Ping of Death and
SYN Flood.

• Blocks unwanted traffic from the Internet to your LAN.

• Blocks access from your LAN to Internet locations or services that you specify as off-limits.

• 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 firewall to log and report attempts to access objectionable Internet sites.

• Permits scheduling of firewall policies by day and time.

1-2 Introduction

v1.0, July 2008

ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual

• Logs security events such as blocked incoming traffic, port scans, attacks, and administrator
logins. You can configure the firewall to email the log to you at specified intervals. You can
also configure the firewall to send immediate alert messages to your email address or email
pager whenever a significant event occurs.

Autosensing Ethernet Connections with Auto Uplink

With its internal 5-port 10/100/1000 Mbps switch and 10/100/1000 W AN port, the SRXN3205 can
connect to either a 10 Mbps standard Ethernet network, a 100 Mbps Fast Ethernet network, or a
1000 Mbps Gigabit Ethernet network. The five LAN and WAN interfaces are autosensing and
capable of full-duplex or half-duplex operation.

TM

The SRXN3205 incorporates Auto Uplink

technology. Each Ethernet port will automatically
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 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 VPN firewall supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol

Configuration Requirements” on page C-4.

(RIP). For further information about TCP/IP, refer to “Internet

• IP Address Sharing by NAT. The VPN firewall allows many 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 (Wired & Wireless) PCs by DHCP. The VPN firewall

dynamically assigns network configuration information, including IP, gateway, and domain
name server (DNS) addresses, to PCs on the LAN and Wireless 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 firewall

provides its own address as a DNS server to the attached PCs. The 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.

• Quality of Service (QoS) support for traffic prioritization.

Advanced VPN Support for Both IPsec and SSL

The VPN firewall supports IPsec and SSL 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 the single-user license of the NETGEAR ProSafe VPN Client software

(VPN01L)

– Supports up to 5 (max) IPsec VPN tunnels (alternately, 4 IPsec VPN tunnels concurrently

with 4 SSL VPN sessions, or 5 IPsec VPN tunnels concurrently with 3 SSL VPN
sessions). The total number of concurrent tunnels and sessions is not to exceed eight.

• 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 or Apple Safari.

– Provides granular access to corporate resources based upon user type or group

membership.

– Supports up to 5 (max) SSL VPN sessions (alternately, 4 SSL VPN sessions concurrently

with 4 IPsec VPN tunnels, or 3 SSL VPN sessions concurrently with 5 IPsec VPN
tunnels).

Wireless Networking Features

• Dual Band Selection. The SRXN3205 allows you to configure one of two bands; choose

between the 2.4 GHz band or the 5 GHz band.

1-4 Introduction

v1.0, July 2008

ProSafe Wireless-N VPN Firewall SRXN3205 Reference Manual

The choice of band is reflected in protocol standard supported, as well as the administration
screens displayed to you. For example, if you choose to enable the 2.4 GHz band, only

802.11b/g/n protocols are supported. In addition, in the administration screens, the
configuration options for 802.11a/n protocols are greyed out. On the other hand, if you enable
the 5 GHz band, the 802.11 a/n protocols are support and the 802.11b/g/n protocol support is
disabled. In this case, the configuration options for 802.11b/g/n protocols are greyed out.

• Multiple operating modes:

– Wireless Access Point. Operates as a standard 802.11a/b/g/n access point.
– Point-to-Point Bridge. In this mode, the SRXN3205 only communicates with another

bridge-mode wireless station or access point. Network authentication should be used to
protect this communication.

– Point-to-Multi-Point Bridge. Select this only if this SRXN3205 is the “Master” for a

group of bridge-mode wireless stations. The other bridge-mode wireless stations send all
traffic to this “Master”, and do not communicate directly with each other. Network
Authentication should be used to protect this traffic.

– Wireless Repeater. In this mode, SRXN3205 does not function as an access point. It

communicates with only repeater-mode, point-to-point-bridge-mode, and point-to-multi­point-bridge-mode wireless stations. Network authentication should be used to protect this
communication.

• Hotspot Settings. You can allow all HTTP (TCP, port 80) requests to be captured and

redirected to the URL you specify.

• Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded easily,

using only your Web browser, and can be also upgraded remotely. In addition to using Web
browser to do so, command-line interface can also be used.

• Rogue AP Detection. The Rogue AP filtering feature ensures that unknown APs ae not given

access to any part of the LAN.

• Access Control. The Access Control MAC address filtering feature can ensure that only

trusted wireless stations can use the SRXN3205 to gain access to your LAN.

• Security Profiles. When using multiple BSSIDs, you can configure unique security settings

(encryption, SSID, etc.) for each BSSID.

• Hidden Mode. The SSID is not broadcast, assuring only clients configured with the correct

SSID can connect.

• Secure Telnet Command Line Interface. The Telnet command line interface enables direct

access over the serial port and easy scripting of the configuration of multiple SRXN3205
across an extensive network via the Ethernet interface. An SSH client is required.

• Configuration Backup. Configuration settings can be backed up to a file and restored.

• Secure and Economical Operation. Adjustable power output allows more secure or

economical operation.

• Power over Ethernet. Power can be supplied to the SRXN3205 over the Ethernet port from

any 802.3af compliant mid-span or end-span source. Please refer to the Appendix for a list of
compliant Netgear PoE switches. ?????

• Autosensing Ethernet Connection with

Mbps IEEE 802.3 Ethernet networks.

• LED Indicators. Power, test, LAN speed, LAN activity, and wireless activity for each radio

mode are easily identified.

• Wireless Multimedia (WMM) Support. WMM is a subset of the 802.11e standard. WMM

allows wireless traffic to have a range of priorities, depending on the kind of data. Time­dependent information, like video or audio, has a higher priority than normal traffic. For
WMM to function correctly, Wireless clients must also support WMM.

• Quality of Service (QoS) Support. You can configure parameters that affect traffic flowing

from the security router to the client station and traffic flowing from the client station to the
security router. The QoS feature allows you to prioritize traffic, such as voice and video
traffic, so that packets do not get dropped.

• VLAN Security Profiles. Each Security Profile is automatically allocated a VLAN ID as each

Security Profile is modified.

Auto Uplink Interface. Connects to 10/100/1000
