If you're using routerboards as your AP's though, and you've got connection tracking turned on, you've still got a vested interest in keeping P2P traffic away from those machines. There is a noticable performance hit when the AP has to track thousands of attempted connections instead of a hundred or so.
QoS is a good idea even without thinking of P2P, especially if you've got a mix of residential and business customers with various bandwidth guarentees.
everybody thanks for you opinion
but, if can not mark in mangle the ARES , i can´t make queues for it, only queues for all P2P less ARES 1.8
my customers, in first time try use Kazaa for example, see the kazaa, no work talk with other users, and the other user anwsers, HI i can download p2p with ares 1.8, the other users kill kazaa, and install the ARES 1.8
all customers in the WISP change to ARES 1.8, aaaagghhhhhhhhh
i can´t mangle , i can´t queues for it, no have control for p2p.
this is my problem.
now, if i am put a new node, or Wisp, i know now, NO STOP the p2p, only put in mangle and queue, the user can use kazaa, bitorrent, and Ares, but slowly, but if stop p2p, uuuuuuuuuuuuuuuuuuuuuuuufffffffff
everybody go to ARES very fast 1.8
what you think??
Thanks in advance
