Applications Depends On Column - Prelogon Policies

L2 Linker

I am trying  to setup prelogon and have a question about the sec policies described in Step 2 of this guide: https://docs.paloaltonetworks.com/globalprotect/9-0/globalprotect-admin/globalprotect-quick-configs/...

 

I assume the source zone would be VPN (applied to tunnel) and the destination zone is Trusted (internal) - correct?

 

Then for permitted applications I added AD, DHCP, DNS and ms-update. The right column notes dependencies. But I believe that when you add the application that those dependencies are automatically added - correct? I don't need to add those manually. Does this look like all I'd need for the prelogon security policy?

Some applications are Implicitly added but some need to be explicitly added. Please check :

When you commit the palo Alto will tell you so no worry, you will know if something needs to be explicitly added if you just pay attention.

@MichaelMedwid,

The firewall is only going to list app-ids that are dependent on other app-ids being allowed, and not what they implicitly use. You can go through applipedia and do some validation checks, but generally speaking you'll need to ensure that those dependent app-ids are allowed to ensure the traffic works as intended.
