VPN works:
VPN English name: Virtual Private Network (virtual private network).
Under normal circumstances, the VPN gateway to double the network card structure, external network card using public IP access Internet.
Terminal A of network 1 (assumed to be the public internet) accesses terminal B of network 2 (assumed to be the intranet), and the destination address of the access packet sent by terminal A is terminal B's internal IP address.
The VPN gateway of the network 1 checks its target address when receiving the access data packet sent by the terminal A. If the target address belongs to the address of the network 2, the VPN gateway encapsulates the data packet according to the adopted VPN technology In addition, the VPN gateway constructs a new VPN packet and takes the encapsulated original packet as the load of the VPN packet. The destination address of the VPN packet is the outer address of the VPN gateway of the second network.
The VPN gateway of network 1 sends the VPN data packet to the Internet. Since the destination address of the VPN data packet is the external address of the VPN gateway of network 2, the data packet will be correctly routed by the Internet to the VPN gateway of network 2.
The VPN gateway of the second network checks the received data packets. If it is found that the data packets are sent from the VPN gateway of the network, the VPN gateway can determine that the data packets are VPN data packets and unpack the data packets. Unpacking process is mainly the first VPN packet Baotou stripped, and then reverse the data packet is restored to the original data packet.
The VPN gateway of the second network sends the restored original data packet to the target terminal B. Since the target address of the original data packet is the IP of the terminal B, the data packet can be correctly sent to the terminal B. It seems the terminal B, it received the data packet and sent directly from the terminal A the same.
The process of packet return from terminal B to terminal A is the same as the above process, so that the terminals in the two networks can communicate with each other.
Through the above description, it can be found that when the VPN gateway processes a data packet, two parameters are very important for VPN communication: the destination address (VPN target address) of the original data packet and the remote VPN gateway address. According to the VPN target address, the VPN gateway can determine which data packets are to be VPN-processed, and the data packets that are not to be processed can be directly forwarded to the higher-level route normally; the remote VPN gateway address specifies the target for the processed VPN data packets to be sent Address, which is the VPN gateway address of the other end of the VPN tunnel. Because the network communication is bidirectional, during the VPN communication, the VPN gateway at both ends of the tunnel must know the VPN target address and the corresponding remote VPN gateway address
