Have my network use neighbors high speed

I set up my neighbors high speed and they have a d-link 624 wireless router.
They actually asked me if I wanted to use their internet.
So I know I have to bridge a connection on a computer in range to use their signal.
I did so.
I bridged a wireless card while their signal was connected with a wired ethernet card that was connected to the wan port on my d-link 524.
I have their router mac addresses filtering so I had to add the addresses.
I added the router and the wireless card on that pc.
Now I can connect to my network and the but no interent over it.
I still get the interent on the "bridged" pc.
What am I doing wrong here?
