About Tom_Access

In the course of tracking down security vulnerabilities, I find myself trying to trace External IPs (from external security scan reports) back to Internal IPs at a specific moment in time (the timestamp from the scan report). Most of the time, it's very simple, as many internal IPs are NAT'd 1-to-1 to external IPs. Those tend to stay static. But there are also large groups of PAT'd addresses, such as whole ranges of internal IPs (like guest WiFi network DHCP pools) that go out a single external IP.   I'm really struggling with how to track these devices down. I can rarely even find a matching internal IP for that timestamp.   Is there a specific NAT/PAT log I can reference? Or a tool for this that I'm missing? I've been trying to use the traffic logs, but that's not always fruitful and it is tedious.   Any suggestions? I'm using a Palo Alto PA-5250 running PanOS 10.2.0.   Thanks in advance, Tom ...
