Limit every vlan (each for 1 appartement)
To 60 down and 9 up
Set the bloat limiter
On your wan with floating rule to the exact up / down you get for your wan connection
A fair method for all users
They have a 60/9 connection protected by a pfS
And you can also tweak the limiters with a time based scheduler
But be aware limiters on 2.6 CE
Are a bit well as far as I know not working
