SMC is proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet at the lowest possible cost, the Wireless BarricadeTM is the convenient, easy solution. About the Wireless Barricade The Wireless Barricade provides Internet access to multiple users by sharing a single-user account. The Wireless Barricade features a WAN interface that allows you to connect either a DSL or cable modem. The Wireless Barricade provides extensive firewall protection and Virtual Private Network (VPN) services. The Wireless Barricade provides many cost-effective functions and management benefits. It is simple to configure and can be up and running in minutes. 1-1 INTRODUCTION Features and Benefits · · · · · · · Internet connection to DSL or cable modem via a 10/100 Mbps WAN port Local network connection via 10/100 Mbps Ethernet ports or 11 Mbps wireless interface (supporting up to 128 mobile users) 802.11b Compliant ­ interoperable with multiple vendors Provides seamless roaming within 802.11b WLAN environment DHCP for dynamic IP configuration, and DNS for domain name mapping Firewall with Stateful Packet Inspection, client privileges, hacker prevention, DoS, and NAT NAT also enables multi-user access with a single-user account, and virtual server functionality (providing protected access to Internet services such as web, mail, FTP, and Telnet) Virtual Private Network support using PPTP, L2TP, or IPSec pass-through User-definable application sensing tunnel supports applications requiring multiple connections Parental controls allows the user to limit certain web sites Email alerts when the users network is being compromise Easy setup through a web browser on any operating system that supports TCP/IP Compatible with all popular Internet applications · · · · · · 1-2 INTRODUCTION 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. · 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 INTRODUCTION · 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 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. 1-4 INTRODUCTION · 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. · · 1-5 INTRODUCTION 1-6 CHAPTER 2 INSTALLATION Before installing the Wireless BarricadeTM, verify that you have the items listed under "Package Contents."

If your ISP used the MAC address of an Ethernet card as an identifier when first setting up your broadband account, connect only the PC with the registered MAC address to the Wireless Barricade and click the "Clone MAC Address" button. This will replace the current Wireless Barricade MAC address with the already registered Ethernet card MAC address. If you are unsure of which PC was originally set up by the broadband technician, call your ISP and request they register a new MAC address for your account. Register using the default Wireless Barricade MAC address. 4-12 CONFIGURING PPPoE THE WIREL ESS BAR RICADE Enter the PPPoE user name and password assigned by your Service Provider. The Service Name is normally optional, but may be required by some service providers. The MTU (Maximum Transmission Unit) governs the maximum size of the data packets. Leave this on the default value (1492) unless you have a particular reason to change it. Enter a Maximum Idle Time (in minutes) to define a maximum period of time for which the Internet connection is maintained during inactivity. If the connection is inactive for longer than the Maximum Idle Time, it will be dropped. Enable the Auto-reconnect option to automatically re-establish the connection when an application attempts to access the Internet again. Attention: Please be aware that the setting "Maximum Idle Time" to "0" and/or "Auto-Reconnect" enabled can cause an increase of your telephone bill if you not operate on a flat-rate. For detailed information contact www.smc-europe.com or your local SMC support team. 4-13 A DV A NCE D SETUP PPTP Point-to-Point Tunneling Protocol (PPTP) allows the secure remo te access over the Internet by simply dialing in a local point provided by an ISP. Using the above scree n allows client PCs to establish a normal PPTP session and provides hassle-f ree configuration of the PPTP client on each client PC For detailed information contact your SMC technical support team. 4-14 CONFIGURING THE WIRELESS BARRICADE Static IP Address If your Internet Service Provider has assigned a fixed IP address, enter the assigned address and subnet mask for the Wireless Barricade, then enter the gateway address of your ISP. You may need a fixed address if you want to provide Internet services, such as a web server, or FTP server. 4-15 ADVANCED SETUP DNS Domain Name Servers map numerical IP addresses to the equivalent domain name (e.g., www.smc.com). Your ISP should provide the IP address of one or more domain name servers. Enter those addresses on this screen. 4-16 CONFIGURING THE WIRELESS BARRICADE LAN LAN IP Use the LAN menu to configure the LAN IP address for the Wireless Barricade and to enable the DHCP server for dynamic client address allocation. Set a period for the lease time if required. For home networks this may be set to "Forever", which means there is no time limit on the IP address lease. IP Address Pool A dynamic IP start address may be specified by the user, e.g. 192.168.2.100 (default value). Once this start IP address has been assigned, IP addresses running from 192.168.2.100 to 192.168.2.199 will be part of the dynamic IP address pool. IP addresses from 192.168.2.2 to 192.168.2.99, and 192.168.2.200 to 192.168.2.254 will be available as static IP addresses. 4-17 ADVANCED SETUP Remember not to include the address of the Wireless Barricade in the client address pool. Also remember to configure your client PCs for dynamic IP address allocation. Wireless Configuration To configure the Wireless Barricade as a wireless access point for wireless clients (either stationary or roaming), all you need to do is define the radio channel, the Service Set identifier (SSID), and encryption options. Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the Wireless Barricade and all of your wireless clients. Be sure you configure all of your clients to the same values. ESSID: The Service Set ID. This should be set to the same value as other wireless devices in your network. Note: The SSID is case sensitive and can consist of up to 32 alphanumeric characters. 4-18 CONFIGURING THE WIRELESS BARRICADE Transmission Rate: Set the data rate transmitted from the Wireless Barricade. The lower the data rate, the longer the transmission distance. (Default: Fully Automatic) Basic Rate: Select "All (1, 2, 5.5, 11Mbps)" from the drop-down list to optimize the data transfer speed for your network. (Default: 1, 2Mbps) Channel: The radio channel through which the Wireless Barricade communicates to PCs in its BSS. (Default: "Auto") Note: The available channel settings are limited to local regulations, which determine the number of channels that are available. Encryption If you are transmitting sensitive data across wireless channels, you should enable Wired Equivalent Privacy (WEP) encryption. Encryption requires you to use the same set of encryption/decryption keys for the Wireless Barricade and all of your wireless clients. You can choose between standard 64-bit or the more robust 128-bit encryption keys. 4-19 ADVANCED SETUP You can automatically generate encryption keys or you can manually enter the keys. For automatic 64-bit security, you enter a passphrase that is used to create four keys (as shown below). The automatic 128-bit security generates a single key by entering a passphrase. 4-20 CONFIGURING THE WIRELESS BARRICADE If you use encryption, configure the same keys used for the Wireless Barricade on each of your wireless clients. Note that the Wired Equivalent Privacy (WEP) protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. NAT Address Mapping Allows one or more public IP addresses to be shared by multiple internal users. Enter the Public IP address you wish to share into the "Global IP" field. Enter a range of internal IPs that will share the global IP into the "from" field. 4-21 ADVANCED SETUP Virtual Server If you configure the Wireless Barricade as a virtual server, remote users accessing services such as web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Wireless Barricade redirects the external service request to the appropriate internal server and port. The WAN interface should have a fixed IP address to properly utilize this function. For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.2.2/8080, then all HTTP requests from outside users will be transferred to port 8080 on 192.168.2.2. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service you provide at the internal address and port to which the Wireless Barricade redirects them. Some of the more common TCP service ports include: HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110. 4-22
