Firewall
The iPAQ Connection Point provides the maximum amount of
security because it can be set to refuse any data from the Internet
that was not requested by a local network device.
When a networked device sends a request over the Internet, the
Network Address Translation (NAT) functionality removes the
unique local address of the device and replaces it with a single
IP address that represents your entire local network to the
Internet.
When a network request is received, the iPAQ Connection Point
remembers which device made the request. The IP address for
the incoming data is then replaced with the local IP address for
the device that requested the data. If the incoming data was not
requested by a network device, the data is blocked.
