3.0 How to Setup and Configure

Follow these directions to reset the Cayman password. This will also set the Cayman back to factory default, meaning none of the previous setting will be saved.

    • Hook up a Serial Cable (DB9Male to DB9Female) to the Cayman and Serial Port (Com 1) on your machine.

    • Set up a connection profile in a terminal emulator program ( Like Hyperterminal). Settings will be:
    9600, 8, N, 1, none.


    • Connect to the Cayman. Once the connection is made hit enter until you get login:

    • Unplug the powercord and then plug it back in.

    • As the Cayman restarts you'll see messages similar to this:
    Cayman PROM Console vX.X
    Cayman-3220 serial XXXXXXX(bootflags 0x1000000)
    STAY IN EPROM?

    • When you see the question "STAY IN EPROM?", hit the Y key a few times. You should come to "CaymanPROM>" or "BootPROM>".

    • Type "erase options" and hit enter.

    • You will be asked, "are you sure?". Type yes and . Make sure you spell out "y-e-s".

    • The options will be erased and you need to type "boot". This will restart the Cayman with the new, clean settings.


After doing these steps you should be able to surf into the Cayman like normal and input your settings.

These instructions are written for Cayman software version 6.3. The same functions can be accomplished in older releases, as well, but the step-by-step instructions would differ.

1) Disable WAN administration to prevent outsiders from gaining control of your LAN:
Connect to the Cayman as 'admin'. Select Configure, then WAN, then "your connection type" (in the "WAN IP Interfaces" box). Then, in the Restrictions control, select "Admin Disabled". Then, you should get a yellow warning icon in the top right of your browser window. Click it, then click the thing that comes up to save your changed settings and restart the Cayman.

2) If WAN administration is not to be disabled, change the name of the SNMP community from the default of 'Public', again to prevent outsiders from gaining control of your LAN:
Connect as 'admin', select Configure, then Advanced, then SNMP (in the Services box). In 'Communities', type a name that only you will know. Just about anything, e.g., 'housebat' or some such nonsense. Click the Add button. Then, select the 'Public' entry and click the Delete button. Save the settings and restart the Cayman.

3) Enable a non-existent default server to trap any unwanted outside server requests:
Connect as 'admin', select Configure, then Advanced, then Default Server (in the NAT box). Check the 'Enable Default Server' box and enter an IP address in the 'NAT Server IP Address' box. The IP should be within your DHCP range, but one that would never be assigned to an actual computer, e.g., 192.168.1.253. Click the Submit button. Save the settings and restart the Cayman.

First, a primer:

Most standard telephone wall jacks are wired with 2 "pairs" of wire to handle two different phone numbers. These pairs are sometimes referred to as the "inner pair" (or line1) and the "outer pair" (line2). By default, the wall jack should be wired so your primary/main phone number uses the inner pair. Your 3220-H (the "newer" one with the blue box logo on the front) is expecting the DSL signal to be present on the outer pair. It should have come with 2 phone cords, one blue and one green. Which one you use is determined by which pair in the wall jack has the DSL signal. Put another way, which line/phone number is subscribed to your DSL service.

To determine which cord to use:

Does your residence have more than one phone number?

If NO, then use the BLUE cord. Note that it is labeled as to what end to plug into the modem.

If YES, is your primary/main phone number the one "subscribed" for DSL service? If YES, use the BLUE cord as above, otherwise use the GREEN.

The problem with all Audio/Video streaming applications is they use dynamic ports. The only thing you may be able to do is run a single NetMeeting session outbound (Cayman can be configured for NetMeeting). This would mean that only the PC behind the router could go out, not the other way around. Also the receiving computer would have to be configured as a NetMeeting server for this to work. It is really important that you understand that this is *one-way only* outbound only, one session only.

This isn't a very desirable solution. Because of the inbound/outbound nature of your desired app, plus the wide range of dynamic ports being used, it is difficult to make this work with any NAT-based router solution, IF you're using standard Dynamic IP addressing.

SOLUTIONS - The alternatives remain temporarily putting the Cayman in bridged mode, turning off NAT and making it function similar to a modem, OR setting up dedicated Static IP to your PC from your ISP. -- Since you want to use this for a one-time only application, maybe bridged mode is the way to go (change back the configuration afterward).
