Filtering and Security using dynamic IP addresses in a school network
My school has just 60Mbps for 400 users. This is static IP bandwidth which is really expensive here in south America: about ($3000 for 60Mbps)/month). My boss can't afford to get us near 500-1000 range at those rates, where we really need to be so each student and teacher can have around 3-5Mbps.
The only solution I see is to buy dynamic bandwidth which is way cheaper. My network admin says its not possible for him to ensure the security of the network if its dynamic IPs- he says he can't filter inappropriate content and provide security.
My thought is there is some software/hardware solution he is not aware of, at least I hope so, as this is the only way we can get the bandwidth up. I can't imagine I am the first person in the predicament and that someone has not figure this out already.
Please let me hear your thoughts, is my network admin correct? Or is there some near/acceptable level of control he can have using a software tool or additional hardware that will make it feasible?
