Firewall policy for VXLAN encapsulated traffic

Hi all

A customer is asking whether their Fortinet devices have the ability to inspect the encapsulated IPv4 payload inside a VXLAN packet?  If so, how is this configured in a policy?

For clarity, I am not asking about how to filter on the VXLAN header details, but the inner packet headers.

The firewalls are not yet built, so if there is any specific code release required, I would be interested.  

Many thanks in advance.
