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.

It is actually a form of IPSec transport mode. You state in the IPSec policy
that you will
'block' rather than negotiate connections to any ports other the TCP 80 or TCP
443 and that
no IPSEc action will take place for connections from anyone to your TCP 80 / TCP
443.
