4. Place the dolphin_status.tcl file in a convenient location on the client computer.
Once Active TCL has been installed, the dolphin_status.tcl file will act as an
executable and can be double-clicked to open.
5. Execute the dolphin_status.tcl file to get the login prompt shown in Figure 21.27 .
You have the option of creating an IPSec tunnel at this time as well. The tcl file
will create a configuration ftle named dolphin in the same directory it is located in.
Tools and Traps
Using Enterprise Wireless Gateways
Don’t think of Dolphin as a full-featured Enterprise Wireless Gateway (EWG).
However, you should consider it a wireless gateway. For a full featured EWG, you
might want to consider one of the more capable and robust (and more expensive)
solutions offered from one of the following vendors:

Bluesocket www.bluesocket.com
Columbitech www.columbitech.com
Reef Edge www.reefedge.com
Sputnik www.sputnik.com
Vernier Networks www.verniernetworks.com
Viator Networks www.viatornetworks.com
These solutions offer the same features as Dolphin—authentication and VPN
support—but they also provide many other options, such as RADIUS server
support, hot failover support, and multiple protocol support (such as WAP, 3G,
and 802.11). The EWG market is still in a great deal of flux as vendors try to refine
their products. That does not mean, however, that you cannot create very secure
solutions using today’s technology. A word of caution, though: You should expect
to find bugs and other errors with most of these solutions because the technology
is still so new. Caveat emptor.
