Yes, it's work with Dummynet well, cause I'm using dummynet for some 
years. The problem is, with dummynet I could not do "borrow" bandwidth 
from the parent.
So, I should move to ALTQ+PF, but unfortunately I'm facing a problem 
with it.
Please give me some comment, If I use ALTQ+PF in my router, it's really 
  could not limit incoming and outgoing traffic from/to my client ?
Does no one have a bettter experience ?

regards,

Dian
