One of the more useful features in troubleshooting on the PIX/ASA (which we used until recently) is the packet tracer, which allows us to enter source/destination IP/port, etc and check to see if a given connection is allowed or blocked, and by which rule. Is there an equivalent feature in the PA units?
We have a very useful packet capture tool embedded in Panos (Monitor tab -->packet capture in GUI).
You can configured several filters and capture traffic in different process stage. (receive, transmit, drop and firewall)
To get security rule matching for a given traffic, you can also use the #test security-policy-match command from CLI.
Speaking of which, what about decrypted traffic?
Can that be captured aswell, and if not - if filing this as a feature request, does the hardware support this in some way (or would it just be a waste of time to describe this feature request)?
I guess it could be done because Wildfire can get a copy of files transmitted by ssl/https and send for analyze.
I'll revive this question - as the answers didn't actually relate.
The Cisco ASA packet tracer allows you to propose a hypothetical flow and runs it through the engine as if it were real. Evaluating the NAT and route dicisions which would likely apply in addition to the policy/ACL allow/deny logic.
It was very helpful to see if your configured configuration should pass traffic you are planning for prior to the actual traffic arriving.
Well it is not that easy with Layer 7 firewall.
If you want to test application sharepoint-admin then session ca go through many steps like incomplete, web-browsing, sharepoint-base, and then get's to sharepoint-admin.
So test would also need to check if every application your requested application depends on is permitted.
But test capability is there.
I know what you are thinking of in the ASA and I don't think there is a Palo equivalent.
You can source your ping/traceroute and the system will tell you the logical response.
> ping source <ip-address-on-dataplane> host <destination-ip-address>
> traceroute source <ip-address-on-dataplane> host 188.8.131.52
But as everyone else stated this will only tell you basic networking/services and not check any of the layer 7 policies in place.
