IPSec Tunnel vs Transport mode vs Filter

I've seen articles which state that IPSec modes are Tunnel and Transport.

Imagine you create an IPSec filter to protect a web server and you apply
that to the server.

Which classification of IPSec 'mode' is that for that specific scenario? To
my view that is neither Tunnel nor Transport, but correct me if I am wrong.
