56 **Functional overview**
57
58 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.

77 * Click Start pass-through, proceed VPN pass-through according to the setting LAN pass-through IP
78 * Click End pass-through to end VPN pass-through
79 * When the device is offline, the Start pass-through button cannot be clicked
80 * When the firmware version of the device is too low, the Start pass-through button cannot be clicked
81 * The current account does not have the permission of pass-through to this device or the device is shared by others, the Start pass-through button cannot be clicked
82 * When the current account has a device being pass-through, the Start pass-through button cannot be clicked
83 * (((
84 After clicking the Start pass-through button, the pass-through is successful, the button changes to End pass-through, and the device status color on the left side changes to yellow

97 === **Status type** ===
98
99 There are 5 status of device in the Wecon VPN pass-through tool.
100
101 * Offline(Gray): Pass-through cannot be performed.
102 * Online(Green): Pass-through can be performed.
103 * Being in VPN pass-through(Yellow): In the status of VPN pass-through.
104 * Reconnecting VPN pass-through(Red): Due to network or other reasons, VPN pass-through is reconnecting.
105 * Ending VPN pass-through(Blue): VPN pass-through is ending.

109 Select device in the device list. You can select "DHCP" or "Static IP".
110
111 * 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.
112 * 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.

118 **How to choose the pass-through IP of the PC.**
119
120 For PLC and PC LANs using the different network segment.
121
122 * 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.
123 * 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.
124
125 For PLC and PC LANs using the same network segment.
126
127 * 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.
128 * 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.
