Cheetah iSharer-3010
The Cheetah iSharer-3010 is a powerful yet simple communication device for
connecting your local area network (LAN) to the Internet. For those who want to surf
the Internet at the lowest possible cost, this Cheetah iSharer-3010 provides a
convenient and powerful solution. It provides Internet access to multiple users by
sharing one or two dial-up accounts. The most outstanding feature of the Cheetah
iSharer-3010 is its two serial ports design for primary/secondary on-demand or dial-
in ports. The Modem2 port can be automatically brought on line by the system to
increase bandwidth under heavy loading. When the traffic falls off, the Modem2 port
will automatically disconnect to save on cost. And if no further request for Internet
resources occur after a period of time, the system will automatically hang up the
connection.
This new Internet access sharing technology provides many cost-effective functions
and management benefits. It is simple to configure and can be up and running in
minutes.

Applications
There are several applications for the Cheetah iSharer-3010, such as:
•
Shared IP Address
The Cheetah iSharer-3010 provides Internet access to multiple users with a
shared IP address. With only one ISP account, multiple users on your network
can browse the Web at the same time.
•
Internet Access
This device supports Internet access via one or two modems. Multiple modems
can be dynamically linked to the Internet based on the current traffic load.
Normally, it is cheaper to use one modem. But, when you require more
bandwidth for heavy usage or downloading large files, using two modems is
faster and more efficient. By configuring the required traffic threshold, the
Cheetah iSharer-3010 can automatically hook up and drop off the second line.
•
Remote Access
The Modem2 port on the Cheetah iSharer-3010 can also support dial-in for
remote access. Remote users can dial-in and access local resources or access
the Internet through the modem connection. An optional callback function is also
provided to reverse charges.
•
Virtual Server
If you have a fixed IP address, you can set up a virtual host for network address
translation. Remote users can access various services using a constant IP
address. Then, depending on the requested service (or port number), the
Cheetah iSharer-3010 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.
•
Security
The Cheetah iSharer-3010 supports firewall security that can deny remote users
access to your network via fixed accounts. It can also deny Internet access to
specified users, or filter all requests for specific services the administrator does
not want to serve.
