[pptp-server] Connect Problems!

Tue Dec 18 08:06:49 CST 2001

Sounds like your isp, try doing a traceroute from client to server port
1723, if that works try the patched traceroute which can use GRE packets.

If it works internally but not over the internet is must be your isp or
other config problem.

Hi George !

First off all again thank for your great support.
I am very sad cause it still is not working

> This is actually a good thing but you need to patch/upgrade your PPPD 
> to support it if it's not done already...

After i received your mail, i checked my pppd and the ppd provided from SUSE
already is patched. As i wrote in my first mail. when i am doing an LAN VPN
connection from any kind of client everything works funtastic.

So i made another LAN VPN connection form an Win2k client, and again it
worked, so i looked at the connection propperties on the win2k client and
they show me, that the vpn connection is using MS Chap V2 and MPPE 128

So my question is, when i can make a LAN VPN connection with MS Chap V2 and
MPPE 128, is it still a missing patch related Problem. Cause when i do the
same over the internet and get the errors written before.

Hopfully you a solution for my problem.

Therfore thanks for your support
Ufuk Altinkaynak

btw: i noticed, that i used in my first mail the word INBOUND, wich was
false translated from me, i wanted to say that it was a LAN connection sorry
for that.
