VPN subnet changes show what they affect before they are confirmed

Before a subnet is added or removed, the page shows how many of the plant's devices sit inside a subnet being removed, and that the plant's on-site agent restarts with the new settings. A warning appears if a subnet overlaps another plant's subnet on the same VPN, or the plant's own direct connection.

• A device whose address is no longer covered stays in the list and is marked "Out of range".
• The address used to test the connection must lie inside one of the plant's subnets.
• 0.0.0.0/0 is not accepted, and the site's own networks are listed instead.
• Removing a plant from a VPN first requires typing the confirmation.
• While the on-site agent picks up the new settings, the page says so and no scan can start.
