this Summer, the school division I work with is planning some overhaul of the network. At the moment there are 16 schools and one board office covering a rather large area. 14 schools have dsl while the other two have dial up. the board office is moving this summer and with the move are putting in a wireless high speed solution that will give the non-dsl schools high speed access as well. They would like to use this to create a WAN VPN for the whole school division and my question is what kind of equipment/cost would I be looking at? Cisco switches at each demarc? routers as a firewall? Not sure if it makes a difference but the schools are running a variety of servers, win2k, win 2003, novell 5, novell 6.5 and there are even some win98 (some the majority in a few schools). I know this may be a lot to digest but any help would be greatly appreciated.
