Hi team,
i m setting up multiple vlan in firepower and vlan are seperated to two interfaces, one interface connect to Nexus switch and one interface connect to Catalyst switch, FW interfaces are trunk mode to each switch. ACL are already allowed between two inside network. all vlan subinterface are inside zone. but it does not pinable between Nexus switch vlan 21 and Calatyst switch vlan 201.
only thing is catalyst sw default gate way point to another router 881.
When i remove default gateway, it stilll does not work.
I have attached the diagram for this. also FW acl rule as well
