Multiple internet connections - some advice
Hi all. Back to basics network advice required here.
Like most schools here in NZ we have seen a huge uptake in internet usage over the last year. We currently have a single 2mb Telecom SchoolZone connection for our internet access and web filtering, and over the last few months have experienced some pretty severe bottlenecks. Senior management are concerned that when the internet connection is saturated because of use in the classroom, it is affecting the 'business' side of the school, and they have asked me for an interim solution until we move to a fibre connection (hopefully at some point towards the end of next year...)
My thought is to purchase a standard business DSL package (which will obviously come with a router), stick that on the network, and use DHCP Reservations and the 'Router' option to point the office/administration PCs to that router for internet.
I'm confused about DNS however. My DC, which is issuing DHCP addresses to my workstations has it's gateway set to our SchoolZOne router and all existing internet traffic goes through this. How do I configure DNS on the DC and workstations to still use the DC for it's primary DNS, then forward to the new router for unresolved queries.
Does that make sense?
