Think of it this way (in very broad and simplistic terms) ...
To get things going, the router connects to the exchange equipment. (Establishes sync).
The router sends ISP login details to the exchange equipment.
The exchange equipment sends a request to the ISP equipment that the router wants a conversation. (PPP session).
The ISP equipment sets up your connection to its routers to the outside world of the web/internet. (Establishes a PPP session).
Job done.
You want to do it in the opposite direction. So do all the hackers in the world.
Someone somewhere, (you), says please let me connect to IP address 123.456.788.123
Your ISP routes that request to the ISP that owns the 123.456.nnn.nnn range.
That ISP says "what the heck?" That router isn't connected at the moment. Sod off hacker!
