ABSTRACT:
There is provided a method for supporting a mobile host in a communication structure having a home agent. The mobile host is enabled to communicate with a Network Address Translation (NAT) server. A packet for the mobile host, incorporating data that includes at least an address and a port used on the mobile host, is translated by the home agent into a global address and a port used on the NAT server, respectively. The packet is sent from the home agent for modification so that the packet can be routed to the mobile host. The packet is compatible with the NAT server.
