can't connect to windows VPN using pptp

Hi,

I've followed the information on fedoraguide.info for configuring PPTP but I'm still unable to connect to my windows VPN

This is what I'm getting in /var/log/messages

the log shows you're using EAP authentication. ms vpn's only like require-mppe, you have to refuse the other authentications:

refuse-pap
refuse-eap
refuse-chap
refuse-mschap
require-mppe

that would go in the /etc/ppp/options.pptp file.

if you're using network manager, go to the advanced settings window, and make sure only MSCHAPv2 is checked. uncheck the others (pap, chap, mschap, eap).

oops, while your in the advanced window, also enable the mppe stuff.
