Qualys Scans through F5's

We are scanning segments on either side of an F5 - the F5 is returning 1000's of IPs to Qualys - even though those IPs are not there.

 

What is the configuration needed on the F5 to prevent this return of 1000's of IPs?

    Which code version and what are you testing using Qualys ?

     

    If you are testing ICMP ping, there is a chance that you have a Forwarding VS with icmp-echo enabled within the VS and this could cause the F5 to respond to seemingly random IP addresses.
