COMMUNICATION CHANNEL BETWEEN AT LEAST TWO PRIVATE NETWORKS

摘要

The invention relates to a method, a network system and a proxy for providing a communication channel from a sending terminal (X) in a first private network (110) to at least one receiving terminal (Y) in a second private network (120), each of which private networks is identifiable by a network address. The private network addresses are mapped to a corresponding proxy assigned addresses, which addresses are informed to the terminals. An originating application packet (1) from a sending terminal (X) to be communicated to the second proxy assigned address, is transformed into a targeti ng packet (2) having a second private network address instead of the second proxy assigned address. The targeting packet (2) is sent to the receiving terminal (Y).
