Reads the export, not the device
ConfigProof reads a configuration export. This control is evaluated against the objects in that file, and it reports what the file says. It does not connect to the device and sees no traffic, so a finding here describes the configuration, not what the firewall is doing right now.
Why it matters
Two objects that cover overlapping ranges under different names let a change reach one set of rules and not the other, so the policy can drift apart without anyone noticing.
How to fix it
Web interface
The steps below are written for the web interface. A finding raised on your own export carries the same steps with your object names filled in.
- Decide which object is canonical and repoint the rules that use the other.
- Where the overlap is deliberate, name the objects so the relationship is visible.
Command line
PAN-OS CLI, standalone firewall, vsys1
set vsys vsys1 address <name-to-keep> description "<merged-description>"An example. Values in angle brackets are yours to supply; a finding on your own export fills in the names it read. Nothing here commits. Review the candidate configuration, then commit it yourself.
Read it back
show vsys vsys1 address <name-to-keep>Values to fill in2
- <name-to-keep>
- The name you are keeping
- <merged-description>
- A description of what this object is for
Before you type it1
- Move every reference to the name you are keeping before removing the other one.
How to confirm the fix
- Confirm every rule that used the removed object still matches the traffic it needs.
Limits
- A summary range and a host inside it are often both legitimate objects.

No benchmark recommendation is mapped to this control in this version.

One complete analysis of one firewall costs nothing. A card is required and nothing is charged.
