Applications
Many advanced applications are provided by the CheetahAccess Wireless Gateway,
such as:
• Flexible LAN Access
The CheetahAccess Wireless Gateway provides connectivity to 10/100 Mbps
wired devices as well as 11 Mbps wireless mobile users. The wireless interface
makes it easy to create a network in difficult-to-wire environments, or to provide
quick access to databases for mobile workers.
• Internet Access
This device supports Internet access through an xDSL, Cable, ISDN or PSTN
connection. Since many DSL providers use PPPoE to establish communications
with end users, the CheetahAccess Wireless Gateway includes a built-in client for
this protocol, eliminating the need to install this service on your computer.
• Shared IP Address
The CheetahAccess Wireless Gateway provides Internet access for up to 253
users with a shared IP address. Using only one ISP account, multiple users on your
network can browse the Web at the same time.
• Virtual Server
If you have a fixed IP address, you can set up the CheetahAccess Wireless
Gateway to act as a virtual host for network address translation. Remote users
access various services at your site using a constant IP address. Then, depending
on the requested service (or port number), the CheetahAccess Wireless Gateway
can route the request to the appropriate server (at another internal IP address).
This secures your network from direct attack by hackers, and provides more
flexible management by allowing you to change internal IP addresses without
affecting outside access to your network.
• User-Definable Application Sensing Tunnel
You can define special applications that require multiple connections such as
Internet gaming, videoconferencing, and Internet telephony. The CheetahAccess
Wireless Gateway can then sense the application type and open a multi-port tunnel
for it.
• DMZ Host 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.
