Tbf limits all bandwidth that leaves the NIC. What you want to do, limit each
connection to a certain bandwidth, is not so easy to implement. If you want
to do it per ip-address, or port, you can create a cbq or htb setup. So you
can put each connection in a different class and limit the speed it can get.
The filtering can be done on ports and/or ip-addresses. But if you want a
class for each connection, you will need a lot of classes.
