2
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.

49 * Offline(Gray): Pass-through cannot be performed.
50 * Online(Green): Pass-through can be performed.
51 * Being in VPN pass-through(Yellow): In the status of VPN pass-through.
52 * Reconnecting VPN pass-through(Red): Due to network or other reasons, VPN pass-through is reconnecting.
53 * Ending VPN pass-through(Blue): VPN pass-through is ending.

55 = **2 **Two modes of Pass-through =
56
57 * **DCHP**: Enables the computer to randomly generate an Ethernet IP. The generated IP segment is determined by the Ethernet configuration of the V-BOX.

106 ✎Note: When using a static IP to connect cloud, you need to set the configure the Preferred DNS Server and Altermate DNS Server. If you are using connecting by other methods, you do not need to configure the Preferred DNS Server and Altermate DNS Server.

133 = **3 Operating Steps** =
134
135 Select device in the device list. You can select "DHCP" or "Static IP".
136
137 * If you select "DHCP", during pass-through, the PC will negotiate with the V-BOX to obtain an available IP address of PC without user intervention.
138 * If "Static IP" is selected, the user needs to fill in the pass-through IP of the PC manually, which will be used for pass-through.

144 **How to choose the pass-through IP of the PC.**
145
146 For PLC and PC LANs using the different network segment.
147
148 * 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.
149 * 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.
150
151 For PLC and PC LANs using the same network segment.
152
153 * 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.
154 * 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.
