Palo Alto, IP Info for rules.
I'm not aware of a simple way using the web based FW management front end to show the raw IP addresses associated with any given security rule. The only approach I've found it to highlight on each object individually to show the value. With object groups, it appears to be even more tedious.
However, if you have acces to the command line, there is a simple command available to show the raw IP addresses associated with rules.
admin@PA850> show running security-policy-addresses
"Test Rule 01; index: 3" {
source [ 10.1.2.1 10.1.2.2 10.1.2.3 10.1.2.4 10.1.2.5 10.1.2.6 10.1.2.7 10.1.2.8 10.1.2.9 10.1.3.1 10.1.3.2 10.1.3.3 10.1.3.4 10.1.3.5 10.1.3.6 10.1.3.7 10.1.3.8 10.1.3.9 ]
destination any;
}
All those IP's on the GUI appear as their object names rather than IP addresses, from the command line though it is easy to identify the IP's should you need to.
