The above figure shows packet forwarding when making communications from PC (10.0.0.100) to the target PC (192.168.0.100) using VPN.

① Create and forward a packet whose dest IP is 192.168.0.100 and whose src IP is 10.0.0.100 from PC (10.0.0.100).

② The original packet is encrypted through the VPN gateway. Add a new IP header (Dest IP: 165.213.87.227, Src IP: 165.213.89.238) to create and forward a new packet.

③ Decrypt the forwarded packet in the VPN gateway. Then, forward the packet to the destination host by referring to the destination IP of the original packet.

④ The PC (192.168.0.100) receives the original packet properly.
