mgetty+pppd dialin problem

[d.s.polyakov at gmail.com]

Hi All!
I`ve installed from the ports mgetty+sendfax on FreeBSD
6.0., pppd been also configured  (options,pap-secrets,chap-secrets).
My server has 2 ethernet interfaces  172.20.0.0/16 and 1 ethernet
interface configured for the real ip+natd
mgetty running due to 'ps aux' and when i try to connect with terminal
everything works and i can login ,but if i try to use ppp proto with
pap authorization ,my connection fails with the following messages in
/var/log/pppd.log :
pppd[671]: pppd 2.3.5 started by root, uid 0
