SOLUTION: When a single IP address attribution server attributes IP addresses to network devices, an access device provides access in a first coverage zone, and an extender access device provides access in a second coverage zone. The extender access device implements MAC address translation for representing network client devices in a second zone. When a network client device roams from the second zone to the first zone, the client device keeps its IP address that was attributed to it by the IP address attribution server via the extender access device even if the client device requests an IP address with its real, non-translated MAC address.EFFECT: The invention enables communication to be continued with an IP address kept even in the case of roaming.SELECTED DRAWING: Figure 8 |
