I'm trying this
set up VPN connection on Windows 7 PC with username & password (using this:

set port forward (port 1723 - unsure if this is right)
it times out when I try to connect (I have no-IP set up so I use a name rather than an IP address to connect to home PC, VNC works fine)
what else do I need to do?
