VLAN Interface, Zone and Security Rule

[SoftMochi]

Hello guys.

always thank you for very helpful advice.

I have a question about VLAN Interface on Palo Alto Firewall.

As you can see below pictures, I made VLAN Interface and L2 Security Zone.

 

also I created security rule which allow internal communication.

but my customer said they cant communication even same zone.

I wonder what is different between FA and FA_Vlan in traffic logs.

I made #4, #6 urgently.

 

anyone knows this problem ?

Thank you.
