A method for accessing a company server by a user terminal through a virtual private cloud network, comprises the following steps: a tunneling router of a company network in which the user terminal is positioned, is allocated with an identifier of the company network from a map server; the tunneling router constructs an authentication path related to an authentication server and the company network based on the identifier of the company network; the tunneling router receives a server address request message for requesting an endpoint identifier (EID) based on a locator identifier separation protocol (LISP) with respect to a company server in which a user terminal attempts to access; and the tunneling router receives the EID of the company server in response to the server address request message through the authentication server, and transfers the EID of the company server to the user terminal. The server address request message may include a source EID information based on the LISP of the user terminal, the identifier of the company network, and an identifier information on the company server.
