Hello Metha,
May you please give more description about differences between using FTD in inline design and transparent. As far as I see they both pass traffic in L2 with NG features.

Transparent mode in FTD came from the ASA which is basically L2 FW and can perform common FW functionalities. Inline FTD is more of a NGIPS and can only perform Firepower functionalities.

Hi Metha,

In my case, I am deploying the FTD with Transparent mode and I have created a Bridge group interface with two select interface members(i.e Inside and Outside). After that I would like to also create inline set with these two interfaces but I could not select them as the interface pair. What is wrong?

Inline set is only for creating interface pair in Routed mode FW for IPS only. For transparent FW, you only need to add interfaces into Bridge group, no inline set is needed.
