How to Deploy a VM with an already used IP Address
⚠️ Warning: Warning: Please note that if all VMs associated with a Tufin Function are deleted, the Tufin Connection will be disrupted. Creating a new VM in the same function (group) will require manual rebuilding of the connections.
Example on VRA Portal
The IP Address of the VM can be found on the network tab.
