Block everyting, only access whatsapp on vlan interface

[SelmanTE]

Hi everybody,

I've Fortigate 80E (FortiOs 5.4.4) and 4 vlans on this firewall.

I need as this config. vlan id 15 must access whatsapp, but it must be ignore all other traffic.

Other vlans have full access for everything.

How can i do it?

Basically with Application Profile and only allow the whatsapp signature. create diff app profiles per rule.
