[pfSense] L2TP encrypted or not?

Indeed L2TP is just a transport protocol. L2TP just handles links between
peers on each side of the tunnel. It's very true to its name, "Layer 2
transport protocol"... That's what it does, and all that it does. Much
like GRE it's common practice in many scenarios to run it over IPSec to take
care of privacy.
One of the big gotchas I experienced when setting L2lTP over IPSec on an ASA
was authentication. Passwords had to be NTLM hashed to work with CHAP. It
took a while for me to figure out why auth kept failing. I see CHAP works
fine with PFSense, I only mention it as a matter of trivia.
