摘要
In a communication system (SYS) an IPv4 private network (IPv4), the global IPv4 Internet (IN) and a IPv6 network (GV6) are interconnected through a first (AGW) and second (BGW) gateway. In order to allow a communication from a first fixed terminal (A1) of the IPv4 private network (PV4) to a second fixed terminal (B) of the IPv6 network (GV6), 'IPv6 in IPv4 tunnels' (TUN' and TUN'') are set up through the IPv4 private network (PV4) and the global IPv4 Internet (IN). In particular, on the basis of a global IPv6 address assigned to the first dual-stack terminal (A1), mapping tables in the first (AGW) and second (BGW) gateway can be set up and are used in the communication between the first terminal (A1) and the second terminal (B). The usage of tunnels (TUN', TUN'') in particular avoid the usage of a Virtual Private Network (VPN) for the communication initiated from the first terminal (A1) to the second terminal (B).
