Zusammenfassung:PURPOSE: A method for providing direct communication in an IP(Internet Protocol) network is provided to enable the direction communication between P2N(Peer-to-Network), P2P(Peer-to-Peer) or an N2N(Network-to-Network) in an IP network. CONSTITUTION: A peer node(P1) requests its own virtual address to a server(100), and the server receives a virtual address request message. The server receives a virtual address request message, and searches the virtual address corresponding to the ID of the peer node(S306). The server includes the searched virtual address in the virtual address response message for the virtual address request message. The server transfers the virtual address response message to the peer node, and the peer node sets up the virtual address included in the virtual address response message to the tunnel interface(S310).
