Problem Description:
MPPE doesnt work correctly with any VPN daemons (such pptpd)
when requesting some URL's such
ya.ru or microsoft.com
Steps to reproduce: download pptpd at http://www.poptop.org/ or any other VPN
daemon that supports MPPE
in /etc/ppp/options.pptpd turn MPPE encryption ON
require-mppe-128
or
#require-mppe-40
Connect to VPN and try goto over vpn : www.ya.ru or microsoft.com (and try to
use windows update)
Explorer freeze while timeout not reach
without MPPE option this site works fine.
I think that it is a bug in the Encrypt Decrypt data To/FROM MPPE
P.S Try connect to ya.ru in telnet and type GET /
when mppe enabled
