wwwBlock
Application for setting a firewall rule that blocks all internet but sustains access to the local network. The rule can be activated or deactivated as long as you have administrator rights.

This tool is succeeded by AfterImage which combines more functions.
 
Features
-Information of current IP settings from selected interface
-Reconfigure hostname and IP settings with optionally prefilled settings
-The "Set Configuration" button only becomes active after all settings are filled following the prefilled settings
 
Description
We had to deploy a fully configured Windows 10 environment to over 50 touchscreen computers. These computers had a single task and were not allowed to access internet resources (except for administrators).
To reach this goal a set of firewall rules were created blocking all traffic beneeth and above the local network IP range. This tool can create, activate and deactivate these firewall rules allowing the administrator by simply pressing a button to get internet access.

The first time wwwBlock is started it elevates itself by registering with the highest privileges. The Windows User Account Control (UAC) will prompt for confirmation. As long as it is started from the same folder this confirmation is not needed after the first run.
