[pptp-server] POPTOP configuration / connection problems / error messages

[Hilary Cheng]

Hi,

    For FreeBSD users, PopTop will use users ppp to connect VPN.
add the following ppp commands to the /etc/ppp/ppp.conf.

pptp:
 set timeout 0
 enable chap
 enable proxy
 set ifaddr 192.10.167.1 192.10.167.101-192.10.167.245  255.255.255.0
 set dns xxx.xxx.xxx.xxx

it will provide a range of ip from 101 to 245. and ur host ip will
192.10.167.1.
also, it will return dns server to ur vpn client.

also, pls add the users name & passwd in the file /etc/ppp/ppp.secret

I have used this configuration with NT/98 w/o any problem. but I donno how
to
makes the internal Lan users can browse the computers that connected via
PPTP.

one more things, it seems that current FreeBSD ppp haven't implemented the
msppe. it can't supported the encrypt channel for VPN. -_-

Regards,

Hilary
