Off course not. As far as I remember ppp (IJJ) and pppd are root-setuid
programs and every user can play with it.
My situation is pretty the same. I've got terminal server which perform telnet
to connect our servers. Although I've got some strange problems (connection
hangs from time to time and then unblock - this could be our local problem)
both ppp deamons works more just fine.
This is my /etc/ppp/ppp.conf (assuming youu've got even empty
/etc/ppp/ppp.secret) file:
default:
enable proxy
set escape 0xff
mydirect:
set ifaddr a.a.a.a b.b.b.b
EOF
where a.a.a.a is IP of the host you telnet to,
b.b.b.b IP adres given to PP client
Routing is set automaticly w/o problem. Aha both adress belongs to she same
subnet so you need just proxy arp to be visible from outside.
So to initiate the PPP connection ypou must execute ppp like this:
$ ppp -direct mydirect
From now on it's ready. Ohh hI would forget to add that there is still
one bug in /usr/src/usr.sbin/ppp/route.c you need to do one thing:
1. Change the line containg 'struct ifreq reqbuf[4];' in GetIfIndex
function . 4 replace with much greater number e.g. 720.
2. Recompile and install.
I'm not sure if you need to it for smal number of ppp interfaces, I have 64
of them and that helped.

PS. I use pppd too. Which is much more comfortable if you write some script
for dynamic IP assigments. If you need some hints write me an email.
