So you are behind router then a hub. This makes your real address converted from xxx.x.xx.xxx to 192.168.1.x then to a hub to your computer. I don't know how to go trough 2 obstacles with LW. If the hub was another router, it could be okay.
Your response wasn't clear enough. And you didn't chech portforward.com which was the first thing I told you to do
I'm sorry I never got into your situation and I think nobody here either, so my help will stop there
Bonne chance
