The default configuration of your router will almost certainly be to block incoming connections, and it may even be locked down tighter than that: if Wifi is enabled, in theory, any old bod in a car on your drive could hack into your intranet and then wander around your network at will. I'm stuck infront of the computer for the next half-hour. If you would like to run through some ideas, I'd be happy to do so, but it would probably be best to do it off list: one, it's unwise to put your setup details (and their weak points) into the public domain(!) and two, I'm not sure what the policies are on this list, but it feels like a moderator may have something to say before very long. Please feel free to email me directly and because I'm a complete stranger, the smart money would be on including a trusted comrade in the dialogue so you have someone to guard your back and take over in half an hour.
