I have a customer who is failing the PCI scan.
The message from the scanner is below. We are using a watchguard firebox. I do not understand what I need to do to make their IP range a trusted range so that they can complete their scan.
> Our scans will originate from the IP range: x.x.x.x/26.
> Please whitelist this range on any active defense mechanism, as applicable.
> Please reschedule a scan.
> The link below explains the need for whitelisting our IP range.
> Perform a Scan without Interference from IDS/IPS at the bottom of Page 14.
> Thank you
