6 VPN pass-through
1 Two modes of Pass-through
- DCHP: Enables the computer to randomly generate an Ethernet IP. The generated IP segment is determined by the Ethernet configuration of the V-BOX.
Static IP：Customize the generated IP address. static mode does not require setting up Ethernet configuration.
1 Enable Ethernet
Wecon VPN pass-through currently supports the following three pass-through modes：
- Ethernet (Networking)
- WIFI (Networking) +Ethernet
- 4G (Networking) +Ethernet
Configure Ethernet networking
When using Ethernet for connecting cloud, it need to configure the Preferred DNS Server and Altermate DNS Server. If you are using 4G/WIFI to connect to the cloud, you do not need to configure the Preferred DNS Server and Altermate DNS Server.
The network segment of the Ethernet IP address, which determines the network segment after using the DHCP VPN pass-through
Configure Ethernet and WIFI networking
At this time, Ethernet is used to connect with intranet and only used as a VPN passthrough. WIFI is used to connect to the cloud.
Configure Ethernet and 4G networking
At this time, Ethernet is used to connect with intranet and only used as a VPN pass-through. 4G is used to connect to the cloud.
2 VPN pass-through
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.

Device information
Display device machine code, name, device status and other information
Start pass-through/End pass-through
- Click Start pass-through, proceed VPN pass-through according to the setting LAN pass-through IP
- Click End pass-through to end VPN pass-through
- When the device is offline, the Start pass-through button cannot be clicked
- When the firmware version of the device is too low, the Start pass-through button cannot be clicked
- 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
- When the current account has a device being pass-through, the Start pass-through button cannot be clicked
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
Refresh
Right-click in the blank area of the device list to pop up the global operation menu.
Right-click menu to select "Refresh" or use shortcut key "F5" to refresh the status.
Status type
There are 5 status of device in the Wecon VPN pass-through tool.
- Offline(Gray): Pass-through cannot be performed.
- Online(Green): Pass-through can be performed.
- Being in VPN pass-through(Yellow): In the status of VPN pass-through.
- Reconnecting VPN pass-through(Red): Due to network or other reasons, VPN pass-through is reconnecting.
- Ending VPN pass-through(Blue): VPN pass-through is ending.
3 Operating Steps
Select device in the device list. You can select "DHCP" or "Static IP".
- 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.
- 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.
How to choose the pass-through IP of the PC.
For PLC and PC LANs using the different network segment.
- 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.
- 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.
For PLC and PC LANs using the same network segment.
- 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.
- 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.
