To change an "Internet" cloud to display the subnet, use the following procedure:
1) Go to the C:\Program Files (x86)\PathSolutions\TotalView\assets\js folder.
2) Edit diagram-layer3.js with a text editor
3) On line 696 it will show:
if (inPubInt(d.subnet) && onlyHasOneDev(d.subnet)) {
return "Internet"; }
Comment out or delete these three lines.
4) Save the file.
5) Do the same for the diagram-layer3.js in the C:\Program Files (x86)\PathSolutions\TotalView\web\assets\js folder.
At this point, do a <CTRL>refresh of your browser and it should show the correct subnet.
