That's a fairly common problem.  If you read the docs closely, you'll 
observe that PPTP uses TCP port 1723, and IP protocol 47 (*not* TCP port 
47).  Allow protocol 47 (GRE), and you should be all good.  By way of 
explanation, have a look at /etc/services (the list of TCP/UDP ports) vs 
/etc/protocols (the list of IP protocols) on any lunix box.
