1 Preface

1.1 Brief Introduction to the DSA-3200

The D-Link DSA-3200 Airspot™ Wireless G Public/Private Gateway is an all-in-one product specially designed to manage and control a Hot Spot environment. The DSA-3200 integrates access control features and wireless network access into a single system to fulfill the basic needs of most Hot Spot venues. The DSA-3200 supports 802.11b and 802.11g wireless transmission modes simultaneously offe ring convenience, efficiency, and a friendly end-user experience from your Hot Spot.

Quick Installation, On-line Immediately

Installation and setup of the DSA-3200 can easily be accomplished without changing the existing network architecture. Within a short time of making all of the necessary physical connections, setup of access security mechanisms can be completed throu gh the Web-based Interface. With the DSA-3200 at the head of a network, Public LAN and WLAN users must authenticate prior to being granted access to the Internet. These users can be assigned a specific bandwidth priority and/or Firewall profile to preserve access rights and privileges between pre-defined user groups.

Friendly Management and Applicati on Interfaces

The DSA-3200 is not only easy to install, but also has a friendly management web interface. The full web-based management interface allows one to operate and maintain the system using a Java enabled web browser. Users that connect to your Hot Spot Network will automatically be redirected to the login page the first time they try to surf the web after connecting to the Public LAN or WLAN Interface of the DSA-3200.

Integrate an Existing User Password Database

Often time organizations or businesses will already own and operate a specific credential database system to centralize and manage their user passwords and user

DSA-3200 Wireless Service Gateway User Manual

permissions on the Network. One of the more prevalent Protocols used to authenticate users is the RADIUS Protocol. With a built-in RADIUS Client the DSA-3200 can support both Local and RADIUS authentication mechanisms simultaneously, allowing one to easily incorporate an existing user password database into the Airspot™ Hot Spot System. The DSA-3200 also provides a built-in user database, allowing dynamic account creation/deletion to coexist with the more static RADIUS database.

3 Managing the D-Link DSA-3200

3.1 Getting Started

This guide will provide information and instruction for administrators of the DSA-3200 Wireless G Public/Private Gateway. This manual corresponds with the version of firmware shipped with the DSA-3200 (v 1.00). From time to time D-Link may release new firmware to add new features or improve on existing ones. These firmware upgrades can be found on the Technical Support Website http://support.dlink.com/ The Support Website also has plenty of great documentation in the way of FAQs and updated manuals, etc. Please take a moment to visit support.dlink.com prior to contacting Technical Support.

3.2 System Concept

The DSA-3200 has the ability to allow or deny access to Network resources based on various types of credentials (IP address, MAC address, or username/password). From a single Broadband Internet connection, the DSA-3200 creates 3 separate networks using NAT, each with its own DHCP server. The WLAN RF interface is an 802.11b/g network that can be configured to either authenticate users or use WPA for enhanced wireless security. The Public LAN interface can be configured to authenticate users so it may serve as a secondary Public access network. The third Private LAN interface does not authenticate users and is intended to service the back office or an existing office network.

Authentication of users is accomplished through any Java enabled Web browser. After a user connects to one of the Public Access networks and attempts to browse the Internet, they will be redirected to a customizable login page hosted on the DSA-3200 without or without SSL encryption. A Walled Garden may be defined to allow users that have not authenticated to access those URLs specified in the Free Surf Zone. Once users authenticate successfully via the Internal Database or an external RADIUS server, the Web browser will once again be redirected to a specified URL. At this point

DSA-3200 Wireless Service Gateway User Manual

the user may freely browse the Internet until the account expires or their connection remains idle longer than allowed. Limits may be impo sed on how l ong a n accou nt may be or the length of time a connection remains idle before it is terminated or even the maximum bandwidth available to the authenticated user.

The DSA-3200 manages all network data that passes through it. Users under the managed network must authenticate in order to access any network resources. User authentication is processed via the DSA-3200 Web server with or without SSL encrypted links. When a user is prompted to login, the DSA-3200 will check the user database to confirm the user’s access rights. In addition to the internal User database for local and On-demand users, the DSA-3200 may query any external RADIUS Server to authenticate and authorize user credentials. If the user fails to successfully authenticate, the DSA-3200 will refuse access and continue to prompt for user log in. If the Administrator so chooses, a list of URLs may be provided for free access to users that have not yet authenticated. Once the user authenticates successfully, the DSA-3200 will grant limited access based on the group membership of the user and redirect the web-browser to the administrator defined URL.

The DSA-3200 can be configured to terminate user access if a user request s to log out or remains idle longer than the configured idle time. Limits can be placed on user session length as well as maximum bandwidth available to specific user g rou ps.

The system is responsible for user authentication, authorization and management. The user account information is stored in the local database, or a specified external databases server. The user authentication is processed via the SSL encrypted web interface. This interface is compatible to most desktop devices and the palm computers.

3.3 Begin Installation

Please follow the Quick Installation Guide included with the DSA-3200 to physically connect the device to the appropriate networks. The QIG also provides instructions to configure the Network interfaces of the DSA-3200 using the Setup

4.1.5 Public WLAN Configuration

The internal 802.11g Access Point serves as a secondary Public Access network. The configurations for the Wireless interface will consist of IP and DHCP selections as well as SSID, Channel, Transmission Mode, SSID Broadcast, and Layer 2 Client Isolation.

DSA-3200 Wireless Service Gateway User Manual

SSID: The SSID is the unique name shared among all devices in a wireless network.

The SSID must be the same for all devices in the wireless network. It is case sensitive and must not exceed 32 characters (any keyboard character is allowed).

Sync to Ticket: Checking this box will enter the SSID of the internal AP in the On-Demand User receipt SSID field.

Auto Channel Selection: The system will automatically select the appropriate channel based on relative noise and interference on available channels when enabled.

Channel: Select the appropriate channel from the list to correspond with your network settings, between 1 and 11 (North America). Channels 1, 6, and 11 tend to have the least amount of overlap in the spectrum.

Transmission Mode: There are 3 Wireless modes available: 802.11b (2.4GHz, 11Mbps), 802.11g (2.4GHz, 54Mbps) and Mix mode (b and g)

SSID Broadcast: If enabled, the SSID will be broadcast in most every 802.11 frame. Disabling this feature removes the SSID from most but not all 802.11 frames to add privacy to your wireless network. When disabled clients trying to join the Network must supply the SSID, as it most likely will not show up in normal Site Survey scans.

Layer 2 Client Isolation: Enabling this feature prevents wireless clients connected to the Internal AP from communicating with one another. This is to ensure the privacy and safety of all guests who use the wireless public access network.

Security: The Security screen is where Wired Equivalent Privacy can be enabled and

configured if so desired. Click the Security Hyperlink.

DSA-3200 Wireless Service Gateway User Manual

WEP Key: Choose to enable or disable WEP on the internal AP. If enabled, any

user attempting to communicate on the wireless network must have the corresponding WEP key configured on their WLAN adapter.

WEP Key Encryption: Choose between a 64-bit (10 HEX or 5 ASCII) or 128-bit (26 HEX or 13 ASCII) WEP key.

Mode: Choose the key format of preference, either HEX (0-9, a-f) or ASCII (any ASCII character).

The Advanced menu allows fine-tuning of the RF characteristics for the internal AP. In most cases the default settings offer the best performance.

DSA-3200 Wireless Service Gateway User Manual

Authentication Type: The default value of Auto allows the AP to auto-detect for

Shared Key or Open System Authentication types. Shared Key requires both the AP

and Client to share a common WEP key (usually Key 1) before the Client can join the Network. Open Key allows any Client to associate with the AP, however if WEP is enabled the client will not be able to communicate unless the correct WEP Key is supplied.

Transmission Rates: The default value of Auto allows data rates to range from 1 to 54Mbps. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can keep the default setting of Auto to have the Access Point automatically select the fastest possible data rate with an Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Access Point and a wireless client.

CTS Protection Mode: The default setting is Disabled. When set to Auto, a protection mechanism will ensure that your Wireless-B devices will connect to the Access Point when Wireless-G devices are present. Keep in mind that the performance of your Wireless-G Network may decrease as a whole to accommodate the slower legacy client.

Basic Rates: The default value is Default. Depending on the wireless mode you have selected, a basic set of supported data rates will be selected. The default setting will ensure maximum compatibility with all devices. You may also choose to enable all data rates by selecting ALL. For compatibility with former Wireless-B devices, select 1-2Mbps.

Beacon Interval: This value indicates the frequency interval of the 802.11 Beacon Frame. The default value is 100 milliseconds. You may enter a value between 20 and 1000 milliseconds. A beacon is a packet broadcast by the Access Point to synchr onize the wireless network.

DSA-3200 Wireless Service Gateway User Manual

RTS Threshold: This value should remain at its default setting of 2346.Should you

encounter inconsistent data flow, only minor reductions are recommended.

Fragmentation Threshold: This value specifies the maximum size for a packet

before data is fragmented into multiple packets. It should remain at its default setting of 2346. A smaller setting means smaller packets, which will create more packets for each transmission. Only minor reductions of this value are recommended.

DTIM Interval: The default value is 3. This value, between 1 and 255 milliseconds, indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Access Point Clients hear the beacons to be informed they will receive broadcast and multicast messages.

IP PNP: Enable this feature to allow Clients configured with Static IP Addresses to be Dynamically routed to the Internet. Client reconfiguration is not necessary with this feature enabled, as long as the Client has Static values for IP Address, Subnet Mask, Default Gateway, and DNS Server Address they will be able to login to the Network and Browse the Internet without changing their IP information.

User Authentication: You can choose to Enable or Disable user authentication for the Wireless Interface.

IP Address: Enter the desired IP address for the Wireless Interface. This will be the default gateway for the Wireless Network.

DSA-3200 Wireless Service Gateway User Manual
