Arrangement for communications between user systems in different networks performs communications as client system interactions via connection server between inner, outer firewalls

摘要

The arrangement has a connection server in a demilitarized zone (2) between inner and outer firewalls and the networks are each formed with at least one client computer (10). A client computer is associated with at least one user system and communications between the user systems takes place as a client system interaction via the connection server. Independent claims are also included for the following: a method of communicating between user systems in different networks, a computer program and a computer program product for implementing the inventive method.
