I have a question related to ip address list control and bandwidth control / metering.
I have an internet pipe where I have 32 public addresses which in turn are distributed for several networks using an L2 switch. Each of these network has their own dedicated firewall which in turn has QOS policies to control bandwidth. Now recently one person who is managing firewall removed the QOS policy to remove bandwidth limitation and was chipping away other networks bandwidth. Now what I need to do is deploy a hardware in place of L2 switch which can control what ip addresses can be used by each firewall/network and bandwidth needs to be controlled / metered even before the packets reach the firewall / network.
Appreciate you advice.. I have seen few devices on the internet like bluecoat packet shaper but looking for expert advice and also need a low cost solution
Thank you in advance
