1st of all u have to be realistic. what is your ratio BW/customer ??

if you cannot buy more capacity than what u have now, you can implement QOS and ensure scavenger and peer 2 peer traffic is dropped.

for example you priorities ur email, DNS service and http.

but I think ur problem is the available BW shared by so many users.

Hi,

which are the configuration timers parameters of the nat fot tcp /udp ? and for the FW inspection ?

with the nbar feature wich P2P protocols the router find ?

can you paste the sh ver/run/nbar configuration ?

I r.taccon I post my config thanks for your help

? Why on the router conf. You choose the:

ip cef load-sharing algorithm tunnel

http://www.cisco.com/en/US/docs/ios/12_2/switch/command/reference/xrfscmd2.html#wp1062329

With the snmp have you check the load-sharing between the serial interfaces (with time frame do you use to pool the interface (5 minutes or less: try 5/10 seconds)?

Are the IP traffic shared well ?
