Strange VPN problem with RRAS in Windows 2003

I try to make a VPN RRAS connection, but seems to come into a odd problem

First, I've tested the VPN (PPTP) connection from a "manual" setup by using "Network Connection" and this work very nice
The above purpose is to check that VPN client and VPN Server works ok

So, I try to make a RRAS out of this (useing technically the same procedure above, but only the Routing and Remote access mmc
When connecting the VPN server says: "LCP terminated by peer
(The VPN server are Linux OS

I've tried to disable "LCP Extenstions" on the client, but does not give anything posetive result

Anyone
