PROBLEM TO BE SOLVED: To provide a remote access system in which performance is not reduced, even when the number of accommodated access terminals is increased, while ensuring security. SOLUTION: The remote access system comprises: a remote terminal 30; an access server 40 accommodating a connections from the remote terminal 30; and first and second logic lines 51, 52 for logically connecting the remote terminal 30 and the access server 40. The remote terminal 30 comprises a flow search processing unit 31 for classifying flows. The access server 40 includes a pass determination processing unit 42 for determining whether a flow can be passed or not, and a flow search processing unit 41 for classifying flows. The first logic line 51 is used for transferring a packet included in a flow to determine whether it can be passed or not by the access server 40. The second logic line 52 is used for transferring a packet included in a flow permitted to be passed by the access server 40. COPYRIGHT: (C)2009,JPO&INPIT
