[pptp-server] VPN under Suse Linux 7.2 through SMC Barricade

[info]

Hi together,

I try to get a VPN established with the following conditions:
VPN Server Suse Linux 7.2 Kernel 2.4.4,
VPN with PPTPD 2.4.0
To access the server, the clients have to go throuh a SMC Barricade 
DSL-Router (PPTP-Port is enabled in the router)
Clients are under W2K

So up to now, it doesn't work so here you get my configs and my messages 
from the linux box:

pptpd .conf:
 > localip 192.168.123.1
 >
 > remoteip 192.168.123.100-199
 >
 > option /etc/ppp/options
 >
 >
 >

etc/ppp/options:
 >
 > name dagobert
 >
 > debug
 >
 > auth
 >
 > +chap
 >
 > +chapms
 >
 > +chapms-v2
 >
 > crtscts
