I know this is a slow response but is probably worth answering since someone will likely search for this again. Had the same problem myself being one of the sites I was struggling with. The problem is the default MTU that pptpd uses. Which is 1300 something.

What you need to do is increase the MTU on ppp0. Since you want this to occur every time a new connection is initiated you need to edit /etc/ppp/ip-up find a space in there and add 'ifconfig ppp0 mtu 1468' that should fix things for you.
