I have an internal network with about 100 users. They connect to a bunch of dumb switches that connect to a PIX 506E that does NAT for them, and afterwards the PIX connects to a 3mbit MLPPP line connected to a Cisco 1721 router.
I need to limit users internet access speed. i.e. 64kbits / sec. per user. I also need to be able to limit the traffic on an application / port basis when necessary. i.e. give priority to port 80 applications.
How would I do that? Would the PIX box be able to do all of these if I upgrade the OS? Or do I need a different solution?
