Call your ISP and ask if your modem has a router mode. There is a good chance it does and is in it (they can also change it to bridge mode, it is often only needed if you run a router), but there is a very slim chance that it is blocking BattleNet. I really cannot think of any other thing it could be... I'll sleep on it and get back to you.
