If you click on 
"preview what has to be done"
you will see one of the lines
Changing permissions of file /usr/sbin/pppd from 105755 to 104755
which removes suid. It is totally stupid.
DO NOT CLICK ON "Activate Changes" All it does is cause trouble. 
Just Quit.
This is one aspect of Linuxconf that is just plain stupid.
I have severe doubts that the writers of linuxconf actually know
anything about security. I know that the people at redhat do not. They
make pppd not suid root, when it is almost useless without that, and
then they make a whole bunch of games suid root.
