Not a firewall

Not working properly your firewall NIS. I want to block access to the Internet program (eg, Google Chrome), perform the following steps: 
Ch. window → Preferences → Network Settings → section "smart firewall" select "program management" → set → choose Gogle Chrome (the program path matches) → right to choose the block → Apply → OK everywhere. 
Now run Google Chrome, but for some reason he can easily download webpage. 
Previously, there was Norton 360, it worked firewall, and NIS pochumu something does not work ...
