Shadow Rule Notice - Really Not a Shadow

I have a firewall (lab unit) with version 9.1 and I configured two Security Policy Rules.

The top rule (1) is Trust to Untrust, a source user is a group, all default options, and an Action of Deny.

The second rule (2) is Trust to Untrust, a source user is a group (different from above), all default options, and an Action of Allow.

 

When I commit the changes I receive a Rule Shadow warning stating rule 1 is shadowing rule 2. The commit succeeds but although both rules are the same, except for Deny and Allow, each is only different by the Source User and I would have thought it would know that. I assume this logic is not included in Shadow checks?

Thanks for any insight.

@jeff6strings,

This is expected logic in the configuration validation, and while 9.1 made it better you won't see any major improvements until you get to utilize 10.0 in production. Thankfully PAN is finally taking notice that this is super annoying and can lead to admins missing more critical things when they essentially get trained to ignore commit warnings.

Hi,

 

I also noticed this behaviour with 9.0.9 (maybe other)...
