Theodore Xu 27.1 3 **Functional overview**：VPN pass-through is to add PC to the Local Area Network where the device is located. It can be imagined that PC "replaces" the device at this time, and PC can access any PLC in this Local Area Network where the device is located.

Theodore Xu 52.1 55 === **How to choose the pass-through IP of the PC.** ===
56
57 For PLC and PC LANs using the different network segment.
58
59 * The PLC is directly connected to the V-BOX, and all IPs that are not used by the PLC can be used in the network segment where the PLC is located.
60 * The PLC and V-BOX are connected through a router or switch, and all free IPs not used by the PLC and other devices on the network where the PLC is located can be used in the network segment where the PLC is located.
61
62 For PLC and PC LANs using the same network segment.
63
64 * The PLC is directly connected to the V-BOX and all free IPs not used by the PLC and other devices on the network where the PLC is located can be used within the network segment where the PLC is located.
65 * The PLC and V-BOX are connected through a router or switch, and all free IPs in the network segment where the PLC is located that are not used by the PLC, other devices on the network where the PLC is located, and other devices on the network where the PC is located can be used.

Theodore Xu 22.1 71 = **2 **Two modes of Pass-through =
72
Theodore Xu 47.1 73 * **DHCP**: Enables the computer to randomly generate an Ethernet IP. The generated IP segment is determined by the Ethernet configuration of the V-BOX.
