Hello, 
I'm trying to implement one pptp vpn between one windows xp and one vpn
concentrator. I've no problems with the Cisco vpn client but I get this
error when I try the windows software:

In the software: The PPP link control protocol was terminated.
In the vpn concentrator: User [xxxx] disconnected. Cannot resolve an IP
address for remote peer.

In debug mode, freeradius gives this output:;

auth: type "MS-CHAP"
  Processing the authenticate section of radiusd.conf
modcall: entering group Auth-Type for request 0
  rlm_mschap: Told to do MS-CHAPv2 for toze3 with NT-Password

        MS-MPPE-Encryption-Policy = 0x00000002
        MS-MPPE-Encryption-Types = 0x00000004

Can someone help me with this? I've search google for some time now and
I still can't solve this.

Regards,
Antonio
