[pptp-server] Bintec X1200 and Linux-Server

[Koop, Lutz]

Hi,

i try to connect a Bintec X1200 ISDN-router via internet with a linux
server. 

HOME (X1200)  ----INTERNET---> Linux server

I have kernel 2.4.17, pptpd 1.1.2 and pppd 2.4.1. When i try a ping from
home to the server i get this in the logfile:
