Version V2.2, July 2005

• Flash memory for firmware upgrade.

• NAT off (classical routing).

Full Routing on Both the Broadband and Serial Ports

You can install, configure, and operate the FWG114P v2 to take full advantage of a variety of

routing options on both the serial and broadband WAN ports, including:

• Internet access via either the serial or broadband port.

• Auto fail-over connectivity through an analog or ISDN modem connected to the serial port.

If the broadband Internet connection fails, after waiting for an amount of time you specify, the

FWG114P v2 can automatically establish a backup ISDN or dial-up Internet connection via

the serial port on the firewall.

• Remote Access Server (RAS) that allows you to log in remotely through the serial port to

access a server on your LAN, other LAN resources, or the Internet, based on a user name and

password you define.

• LAN-to-LAN access between two FWG114P v2 wireless firewall/print servers through the

serial port, with the option of enabling auto-failover Internet access across the serial

LAN-to-LAN connection.

802.11g and 802.11b Wireless Networking

The FWG114P v2 Wireless Firewall/Print Server includes an 802.11g-compliant wireless access

point. The access point provides:

• 802.11b standards-based wireless networking at up to 11 Mbps.

• 802.11g wireless networking at up to 54 Mbps, which conforms to the 802.11g standard.

• WPA and WPA2 enterprise class strong security with RADIUS and certificate authentication

as well as dynamic encryption key generation.

• WPA-PSK and WPA2-PSK pre-shared key authentication without the overhead of RADIUS

servers but with all of the strong security of WPA and WPA2.

• 64-bit and 128-bit WEP encryption security.

• WEP keys can be generated manually or by passphrase.

• Wireless access can be restricted by MAC Address.

Introduction 2-3

Version V2.2, July 2005

• Wireless network name broadcast can be turned off so that only devices that have the network

name (SSID) can connect.

Virtual Private Networking

The FWG114P v2 Wireless Firewall/Print Server provides a secure encrypted connection between

your local network and remote networks or clients. Its VPN features include:

• Support for up to 2 simultaneous VPN connections.

• Support for industry standard VPN protocols.

The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P v2 supports standard

keying methods (Manual or IKE), standard authentication methods (MD5 and SHA-1), and

standard encryption methods (DES, 3DES). It is compatible with many other VPN products.

• Support for up to 168 bit encryption (3DES) for maximum security.

• Support for VPN Main Mode, Aggressive mode, or Manual Keying.

• Support for Fully Qualified Domain Name (FQDN) configuration when the Dynamic DNS

feature is enabled with one of the supported service providers.

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. Time-dependent information such as video or audio will

have a higher priority than normal traffic. For WMM to function correctly, wireless clients must

also support WMM.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the FWG114P v2 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.

• 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.

2-4 Introduction

Version V2.2, July 2005

• Logs security incidents.

The FWG114P v2 will log security events, such as blocked incoming traffic, port scans,

attacks, and administrator logins. You can configure the router to e-mail the log to you at

specified intervals. You can also configure the router to send immediate alert messages to your

e-mail address or e-mail pager whenever a significant event occurs.

• With its content filtering feature, the FWG114P v2 prevents objectionable content from

reaching your PCs. The router allows you to control access to Internet content by screening for

keywords within Web addresses. You can configure the router to log and report attempts to

access objectionable Internet sites.

Security

The FWG114P v2 Wireless Firewall/Print Server 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

router allows you to direct incoming traffic to specific PCs based on the service port number

of the incoming request, or to one designated “DNS” host computer. You can specify

forwarding of single ports or ranges of ports.

Autosensing Ethernet Connections with Auto Uplink

With its internal 8-port 10/100 switch, the FWG114P v2 can connect to either a 10 Mbps standard

Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are

autosensing and capable of full-duplex or half-duplex operation.

The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically sense

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 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.

Introduction 2-5

Version V2.2, July 2005

Extensive Protocol Support

The FWG114P v2 Wireless Firewall/Print Server supports the Transmission Control Protocol/

Internet Protocol (TCP/IP) and Routing Information Protocol (RIP).

• The ability to enable or disable IP address sharing by NAT.

The FWG114P v2 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. This feature can also be turned off completely for using the FWG114P v2 in

settings where you want to manage the IP address scheme of your organization.

• Automatic configuration of attached PCs by DHCP.

The FWG114P v2 Wireless Firewall/Print Server 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 router provides its own

address as a DNS server to the attached PCs. The router 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 Entersys or WinPOET on your computer.

• PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.

• Classical IP (RFC 1577).

Some Internet service providers, in Europe for example, use Classical IP in their ADSL

services. In such cases, the wireless access point is able to use the Classical IP address from

the ISP.
