In a data communication system according to the invention the functionality of the gateway device is distributed in a data communication network thereby reducing the need to direct the data traffic from and to terminals (212, 213, 214) through a single point in the data communication network. A first data communication device (207) is arranged to make, through signalling, second data communication devices (204, 205, 206) capable of directing the data communications of the terminals to the starting points of the respective logical data communication tunnels (215, 216, 217). This way there is no need for all logical data communication tunnels to start from, or depending on the direction, to end at, the same point in the data communication network. |
