Problem connecting to pptpd server

Hi everyone,

I'm trying to setup a Debian 7 server to CentOS 6 server VPN connection 
with PPTP.

The connection isn't established and I'm stuck with the following 
message on the CentOS pptpd server :

reached, extra IP addresses ignored

I've been working on this for days and I have no clue of what's going on.

Please, help.
