Applications

Many advanced applications are provided by the Wireless Barricade, such as:

• LAN Access

The Wireless Barricade provides connectivity to 10/100 Mbps devices, making it easy to create a network in small offices or homes.

• Internet Access

This device supports Internet access through a DSL or cable connection. Since many DSL providers use PPPoE to establish communications with end users, the Wireless Barricade includes a built-in client for this protocol, eliminating the need to install this service on your computer.

• Shared IP Address

The Wireless Barricade shares a single IP address with up to 253 users. Using only one ISP account, multiple users on your network can simultaneously browse the Internet.

NTRODUCTION

•Virtual Server

If you have a static IP address, you can set up the Wireless Barricade to act as a virtual host for network address translation. Remote users access various services at your site using the static IP address. Then, depending on the requested service (or port number), the Wireless Barricade routes the request to the appropriate server (at an internal network IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal network IP addresses without affecting outside access to your network.

1-3

NTRODUCTION

• User-Definable Application Sensing Tunnel

You may define special applications that require multiple connections such as Internet gaming, video conferencing, and Internet telephony. The Wireless Barricade will then sense the application type and open a multi-port tunnel for it.

• DMZ Hosts Support

Allows a networked computer to be fully exposed to the Internet. This function is used when the special application sensing tunnel feature is insufficient to allow an application to function correctly.

• Security

The Wireless Barricade supports security features that deny Internet access to specified users, or drop requests for specific services. The Wireless Barricade’s firewall also blocks common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

• Virtual Private Network

1-4

The Wireless Barricade supports three of the most commonly used VPN protocols – PPTP, L2TP, and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, then any of these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally shared data network). The VPN protocols supported by the Wireless Barricade are briefly described below.

NTRODUCTION

• Point-to-Point Tunneling Protocol – Provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs.

• Layer Two Tunneling Protocol – Includes most of the features provided by PPTP, but has less overhead and is more suited for managed networks.

• IP Security – Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication.

Hardware Description

The Wireless Barricade Broadband Router may be connected to the Internet or to a remote site using its RJ-45 WAN port. It may be connected directly to your PC or to a local area network using any of the four 10/100 autosensing switch ports.

These RJ-45 ports auto-negotiate the operating speed (10/100 Mbps) and the duplex mode (half/full duplex).

Access speed to the Internet depends on your service type. Full-rate Asymmetric Digital Subscriber Line (ADSL) provides up to 8 Mbps downstream and 640 Kbps upstream; G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 Kbps upstream; Cable modems provide up to 36 Mbps downstream and 2 Mbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.

Though Internet access speed is determined by the modem type connected to your Wireless Barricade, data passing between devices connected to your local area network can run up to 100 Mbps over the Fast Ethernet ports.

The Wireless Barricade includes LED indicators on the front panel that simplify installation and network troubleshooting.

TCP/IP Configuration

To access the Internet through the Wireless Barricade, you must configure the network settings of the computers on your LAN to use the same IP subnet as the Wireless Barricade. The default network settings for the Wireless Barricade are:

IP Address: 192.168.2.1 Subnet Mask: 255.255.255.0

Note: These settings may be changed to suit your network requirements,

but you must first configure at least one computer as described in Chapter 5 to access the Wireless Barricade’s web configuration interface. (See Chapter 4 for information on configuring the Wireless Barricade.)

If you have not previously configured TCP/IP for your computer, refer to “Configuring Client TCP/IP” on page 5-1.

All PCs connected to the Wireless Barricade must be in the same IP subnet as the Wireless Barricade. The default IP address of the Wireless Barricade is 192.168.2.1 (where x means 2–254) and the subnet mask is

255.255.255.0. You can set the IP address for client PCs either by automatically obtaining an IP address from the Wireless Barricade’s DHCP service or by manual configuration. See “Setting Up TCP/IP to Work with the Wireless Barricade” on page 5-5.
