INSYS GPRS 5.1 serial

8.4.1 Fixed IP address and VPN connection

The service provider mdex (http://www.mdex.eu) offers the service "fixed.IP".
With this service, one or more devices in a virtual private network can be ad-
dressed. SIM cards are thus grouped to form a closed network with a private IP
address area. Connections from the company network to the devices will then be
established via a VPN tunnel.
The service fixed.IP from mdex will enable GPRS devices to communicate with
each other as well as with computers in the Internet via a VPN connection.
