ASA Transaparent mode use of subinterfaces

[ziqex]

Hi,

I wanted to use subinterfaces in the asa transparent mode but was only able to reach the ASA BVI but not any other IP.

However, when I started using physical interfaces, I was able to reach everything. The rest of the config remain the same. Is this done by design in transparent mode of ASA? Thanks

 Initial config – only BVI address reachable the rest unreachable

interface GigabitEthernet1/5.753
description CLEAN
bridge-group 75
nameif VLAN-753
security-level 50
!
interface GigabitEthernet1/6.754
description DIRTY
bridge-group 75
nameif VLAN-754
security-level 50
!

then changed to physical interfaces and everything was reachable 

interface GigabitEthernet1/5
description CLEAN
bridge-group 75
nameif VLAN-753
security-level 50
!
i
!
interface GigabitEthernet1/6
description DIRTY
bridge-group 75
nameif VLAN-754
security-level 50

Thanks

@ziqex the interface configuration looks ok.

I think previously I had to explictly configure the switchport configuration to trunk on the switches, before I could communicate through the ASA.

interface GigabitEthernet0/0 
 switchport trunk encapsulation dot1q
 switchport mode trunk
