Firepower Thread Defense virtual in transparent mode using VMWare

Hello Community,

I'm trying to configure FTDv in transparent mode but I'm encountering an issue. The initial configuration is okay but when connecting hosts (one connect to inside VMnic and the other to outside VMnic) they exchange with each other without passing through FTDv, certainly because FTDv's inside, outside, and the both hosts VMnic are in the same VLAN.

I want to know how to pass the traffic through the FTDv IPS from INSIDE (hostA) toward OUTSIDE (hostB).

thank you for your response

Hi,

For any transparrent mode deployment, you have to choose different vlans for the interfaces. in your case, you can choose different vlan for inside and outside interface.

Hello Muhammad,

Thank you for the response.

Same IP Range but different VLANs, right?

Yes, that's correct. Same IP range and different vlans.
