VLAN IDs must be unique across different subinterfaces.

Hi marvin,

Unique Vlan ID meaning, you mean to create same Vlan ID in Diferent subinterfaces.. which is not allowed in the FMC.

let me make it more clear about my challenge: i am trying to configure with inside interface as trunk allowing Vlan 3,4 ,5   than pass the same to outside interface with the same Vlan 3,4,5  this senario i am trying to put the FTD create between the servers communication within the same vlan 3,4,5. i hope it is clear.

Passing the same VLAN from inside to outside implies you are using transparent mode vs. the much more common routed mode. Is that what you are trying to do?

Yes i have configured the FTD in Transparent Mode, but i am not getting any luck it is not working i need some advise.. whether it will work or not..?/

Any Advise how to do it , that will be appreciated.
