Reads the export, not the device
ConfigProof reads a configuration export. This control is evaluated against the objects in that file, and it reports what the file says. It does not connect to the device and sees no traffic, so a finding here describes the configuration, not what the firewall is doing right now.
Why it matters
A security rule for one group cannot tell its users from the other group's by source address, so every rule written for one applies to both.
How to fix it
Web interface
The steps below are written for the web interface. A finding raised on your own export carries the same steps with your object names filled in.
- Give each agent tunnel profile its own IP pool under the gateway's Agent, Client Settings, and write the rules against those ranges.
Command line
PAN-OS CLI, standalone firewall, vsys1
set vsys vsys1 global-protect global-protect-gateway <gateway> remote-user-tunnel-configs <object-name> ip-pool <ip-pool>An example. Values in angle brackets are yours to supply; a finding on your own export fills in the names it read. Nothing here commits. Review the candidate configuration, then commit it yourself.
Read it back
show vsys vsys1 global-protect global-protect-gateway <gateway> remote-user-tunnel-configs <object-name>Values to fill in3
- <object-name>
- The object's name, as it appears on your firewall
- <gateway>
- The name of the GlobalProtect gateway
- <ip-pool>
- The IP pool this profile hands out, different from every other profile's on the gateway
How to confirm the fix
- Connect a user of each group and confirm the two receive addresses from different pools.
Limits
- A pool that is not an IPv4 network, range or address is compared by name only.
