So... It's ok what you want to do.
Let's say 192.168.10.1-255 for your computer lab
192.168.20.1-255 for the office &
192.168.30.1-255 - classroms
You have to make a linux box to become the router for 192.168.X.X (if
the router provided by telco is not a computer able to masquarade).
I recommend you to run a proxy server on this computer. You can also run
the dns server (no. of clients<500). So, telco's class could be:
A.B.C.1 - router
A.B.C.2 - dns server / proxy / masq
A.B.C.3 - web server
A.B.C.4 - mail server
But... you should assign this ips by yourself.. i dont know exactly
your projects, etc.
For details about configuring (kernel options, routes, firewall, etc.)
send me a message.
