Looking for Router with LAN MAC Address Filtering

[Konfucius]

As the title says I need a router with MAC Address Filtering.

But I need it for LAN, a W-LAN MAC Filter won't be of any use to me.

 

I live in a hall of residence (at least according to the dictionary) and I share a seperate internet connection with my friends. We still use the network everyone else in the house uses but have a different internet provider. So we want to be able to block the other users from using our connection.

 

 

Any suggestions? My internet research wasn't very successful so far.

Thanks in advance.
