Abstract
A VPN server encapsulates a packet P2 upon receiving the packet and distributes packets P (2-1) and P (2-2) to wireless terminals MN1 and MN2 respectively. The wireless terminal MN1 decapsulates the packet P (2-1) (as packet P2-1) upon receiving the packet and transmits the packet P2-1 to a wireless terminal MN3. Thus, the packet is transmitted by a communication path: file server 102—VPN server 101—wireless terminal MN1—wireless terminal MN3. The wireless terminal MN2 decapsulates the packet P (2-2) (as P2-2) upon receiving the packet and transmits the packet P2-2 to the wireless terminal MN3. The packet P2-2 is transmitted by a communication path: file server 102—VPN server 101—wireless terminal MN2—wireless terminals MN3.
