Test your firewall

Do you think your firewall does its job? Download LeakTest, a simple utility that tries to establish a connection to an internet server. Within one second you’ll know whether your firewall protects you against any possibly dangerous application connecting to the internet or not.

You want to push the limits? Rename the file LeakTest.exe (for example ‘putty.exe’) and check whether your application-based firewall is smart enough to detect this ‘cheat’.
