Allow Intranet, Deny Internet

Hi all,

Is it possible to allow an application such as Intenet Explorer to access the local Network but not the Internet.

Example : Gateway to Internet > : Allowed

I have tried adding a rules but iexplore asks for access to and once this is given it can access everything. I’ve tried blocking its access to the gateway but this has not effect.

Is this possible?

Thanks in advance.

What app is listening on 12080? A proxy?
