Abstract
A method and a system for enabling routing of traffic to/from a roaming host node roaming from a subnet of a home network to a visited network, the roaming host node assigned an IP address in the home network. The method comprises configuring, in a router of the visited network to which the roaming host node is connected, a subnet by assigning an IP address range to the subnet, the assigned IP address range being the same IP address range of the subnet of the home network; creating/configuring a tunnel between a router of the home network and the router of the visited network; and creating/configuring, in the router of the home network, a static route to route traffic destined to the roaming host node the traffic is routed through the tunnel, the IP address of the roaming host node being maintained unchanged in the subnet of the visited network.
