I am upgrading my pptp to 1.1.2.
I have some dudes...

I do  ./configure and I read...
[...]
===============================================================================
Configuration chosen:
   PPPd IP allocation: No.
   PPPd:               Standard.
   LIBWRAP security:   No.
   Mode:               IP tunneling server (PAC).
===============================================================================
[...]

What is that?
How can I use libwrap security?
Is there any other modes for pptp or only 'IP tunneling server (PAC).'?

Thanks
