Establishing communication with remote devices behind the gateway via TCP / IP

The system structure and neccessary steps are given on the diagram:

You must enable the virtual IP address function for the specified WebHMI node on Level2 In the WebHMI / Virtual IPs tab, add a 'virtual' address from the VPN network (an additional address allocated to the end devices you need to access). </p>

After adding this address, the rules for translating the virtual vpn address data to the actual addresses of the end devices in the WebHMI LAN subnet will be automatically generated. You also need to set up a masquerading for the LAN zone.

For our u-remote example, this is the address 192.168.0.210. Then, to configure the u-remote device via a web browser (u-remote has its own web interface for configuration), it is sufficient to specify its address from the WebHMI VPN.

Similarly, it would be possible to program remotely the PLC and other automation devices with an Ethernet interface.
