Your Cayman 2E-H-W11 connects the personal computers, printers, and other network
devices in a workgroup to a remote network or the Internet. Your Cayman 2E-H-W11
functions include the following:
•Awireless bridge that interoperates with 802.11b wireless networking devices,
including wireless networking cards from Cisco, Lucent, Apple, and 3Com.
• An integrated eight-port Ethernet hub on the Cayman 2E-H-W11 front panel that
lets you add or move workgroup network connections quickly and easily.
• An auto-configuring Internet router that incorporates Cayman's Swift-IP™
technology.
Cayman 2E-H-W11 features include the following:
•Full-featured wide area network bridge supports wide range of non-TCP/IP
protocols.
•Web-based browser configuration makes configuration and management easy from
anywhere on your network. Command-line configuration lets you monitor the
Cayman 2E-H-W11 through a Telnet or VT100 connection.
•Network Address Translation (NAT) lets your workgroup network share one IP
address when communicating with other hosts on your corporate network or the
Internet.
•Dynamic Host Configuration Protocol (DHCP) client functionality lets a DHCP
server on your wide area network configure the IP address and other network settings
for the WAN interface on your Cayman 2E-H-W11 automatically.
•DCHP server functionality lets the Cayman 2E-H-W11 automatically configure the
IP addresses and other network settings for computers on your local area network.
•IP pinholes let you provide web services, mail services, or FTP services from your
local area network without compromising network security.
•Enhanced security features, including restrictions on administrative access to the
router over its WAN port, broadcast filtering to prevent denial-of-service attacks, and
rejection of packets with “spoofed” IP addresses.
•Bandwidth shaping lets carriers and service providers regulate the flow of traffic
through the WAN port in 64kbps increments.
Introduction
Configuring Your
Cayman 2E-H-W11
To configure the Cayman 2E-H-W11, you need a computer on the same TCP/IP network as
the Cayman 2E-H-W11. Perform Steps 1 and 2 of “Configuring Your Computer” on page 3
for information on how to configure your computer to use an IP address on the
192.168.1.0 network.
1. Determine whether your Internet Service Provider (ISP) has supplied you with
a Configuration Worksheet identifying the settings you are to use when
configuring your Cayman 2E-H-W11.
• If you received a Configuration Worksheet, refer to it when configuring your
Cayman 2E-H-W11.
• If you did not receive a Configuration Worksheet, your Cayman 2E-H-W11 has
already been configured, and no action on your part is needed. You can skip this
section or perform the steps to review your Cayman 2E-H-W11 configuration.
2. Identify the wireless network ID for your Cayman 2E-H-W11.
The default wireless network ID consists of the words “Cayman-2E” and the serial
number of the gateway. You will need to configure your laptops and other devices
with this wireless ID if you want them to connect to the Cayman 2E-H-W11 over a
wireless network link.
3. Run a Web browser application, such as Netscape Navigator or Microsoft
Internet Explorer, from the computer on the same network as the
Cayman 2E–H-W.
Refer to page 3 for information on how to configure your computer.
4. Open a session to your Cayman 2E–H-W11.
Enter http://cayman-2e or http://192.168.1.254 in the Location text box. The browser
displays the Cayman 2E-H-W11 QuickStart window.
If your Configuration Worksheet tells you to use an IP address other than
192.168.1.254 to log in, enter http://<
ip-address
>.
5. Transfer the contents of each field on the Configuration Worksheet to the
corresponding field in the QuickStart window.
6. If you changed any of the fields in the QuickStart window, click the Save
button to save the modified Cayman 2E-H-W11 configuration.
7. When you see the Cayman 2E-H-W11 Home page, click the Restart Cayman-2E
button to restart your Cayman 2E-H-W11 with its new configuration settings.

Setting Up Your
Cayman 2E-H-W11
1. Unpack your Cayman 2E-H-W11 shipping carton.
You should have the Cayman 2E-H-W11, a power transformer, an installation CD-
ROM, and printed documentation.
2. Connect the Cayman 2E-H-W11 to the devices on your LAN Ethernet network.
Connect each computer or other device to a hub port on the front of the Cayman 2E-
H-W11 with a twisted-pair Ethernet cable (maximum length 100 meters).
The following instructions assume that you want all devices on your workgroup Ethernet
network to use IP addresses on the 192.168.1.0 network. If your workgroup network must
use another network number, refer to the Cayman 2E-H-W11 documentation for
information on how to change the IP address of the LAN interface for the Cayman 2E-H-
W11.
1. Configure your computer to use an IP address on the same TCP/IP network as
the Cayman 2E-H-W11.
•Windows 95/Windows 98/Windows NT/Windows 2000
1 Open the Network Control Panel and select the TCP/IP service for the
Ethernet card in your computer (for example, TCP/IP ->3Com EtherLink III).
2 Open the Properties window.
3 Click the Gateways tab, and remove any installed gateways.
4 Click the DNS Configuration tab, and disable DNS.
5 Click the IP Address tab, and click the Obtain an IP Address Automatically
option button.
6 Click OK to save the modified TCP/IP settings.
•Macintosh – If your Macintosh uses Open Transport, open the TCP/IP Control
Panel and choose Connect via Ethernet. Choose Configure Using DHCP Server
and enter the IP address of the Cayman 2E-H-W11 (192.168.1.254) in the Name
Server Address text box.
If your Macintosh uses MacTCP, open the MacTCP Control Panel and select the
Ethernet interface icon. Enter 192.168.1.x(where xis any number in the range 1-
253) in the IP Address text field. Click the More button. Click the Obtain Address
Manually radio button. Enter 192.168.1.254 in the Gateway Address text field.
Pull down the Class dropdown list and choose C, which sets your subnet mask
to 255.255.255.0. In the Domain Name Server Information fields, enter your
Internet Service Provider’s domain name in the Domain text field and enter
192.168.1.254 in the IP Address text field.
2. Restart your computer.
3. Configure each computer that will use the Cayman 2E-H-W11’s address sharing
feature to use DHCP, as described in Step 1, above.
Configure devices that will not use DHCP with static IP addresses on the same
network as the Cayman 2E-H-W11. Restart each device after you have updated its
TCP/IP configuration.

3. Connect the Cayman 2E-H-W11 to your WAN Ethernet network.
For example, connect the WAN port to your cable modem, xDSL modem, or
backbone network.
4. Connect the power transformer to the power jack on the Cayman 2E-H-W11
back panel. Plug the power transformer into an appropriate electrical outlet.
Note: At this point, if your Cayman 2E-H-W11 can obtain network information
from a DHCP server on its WAN interface, your Cayman 2E-H-W11 is completely
functional. If a DHCP server is not available, you must configure the IP address
information on the Cayman 2E-H-W11 WAN port (see page 4). Because the
operating software for your Cayman 2E-H-W11 is installed during factory
verification, you do not need to run the Cayman 2E-H-W11 installer utility before
using the device.
