Hello!
Add the USG6000V device and a Cloud.
Then move the mouse cursor to the Cloud and click it.

Enter the Cloud configuration interface, add a network card (for example local link 4) and then add more UDP protocols. When you need to manage multiple devices, you need to add a UDP for each device. For example, if you need to manage 3 devices, you need to add 3 UDP's.
And then you need to add port mapping for each UDP and network card. Please note that the network adapter's import number is always consistent with the serial number of the network adapter.
Thanks!
