Cannot ping FTD subinterfaces

[JACQUES DU PLESSIS]

Hi Guys, 

We have some FTDs configured as DC firewalls, but the servers in those VLANs are not able to ping their gateway (FTD subinterfaces). Routing and policies work normally, but some systems need to be able to ping their gateway before their system setup actually will continue. Any ideas?

Thanks!

Is the trunking to the subinterfaces passing traffic (not blocking the tagged VLANs and STP forwarding from the downstream switch to the FTD)?
