What is the difference between intranet and internet???

Probably you are thinking about local 192.168.*.* networks. BUT:

At our university the "local" network is public ip addresses 141.48.*.* (with 
subnets). You can go block everything that is not the local subnet, but that 
will definitely block the virus-definition updates from the central server. And 
it will also block all "intranet"-access to other machines of the same 
workgroup but in a different subnet. Both are very bad results of your 
thinking. And we aren't yet talking about the os-dependent ways of 
implementing it. If the user even has enough rights to do such a stuff.

I think your question is not only offtopic but also wrong in the sense that you 
have to think about the task much more...
