Inter-VLAN Routing configuration in Firepower

Hi

I would like to configure inter-vlan routing in firepower(FMC) using VLAN sub interface.

I've created sub interfaces with separate VLAN ID on physical interface. And I've configure trunking port at the access switch side with appropriate gateway.

But the inter-vlan is still not working .

What do I need to do in Firepower (FMC) in order to work inter-vlan routing?


Thank you so much all!

I am configuring on FMC 6.7 to FDM 1120 in routed mode with 4 inside interfaces and a single outside interface--have the same problem. I allow inside to inside traffic but cannot pass traffic between inside interfaces. Screenshot 2021-04-06 212402.pngScreenshot 2021-04-06 212723.png
