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.
