[Manage Netwoks] section >> Block not working!!??

I’ve blocked the Interface related to Wireless Network that I’m using,But still can access web ,etc.What’s wrong?? :-\

Can someone explain what this part of CFW is supposed to do??Does it really work for others? :-\

Bullhead, are you referring to this area of CIS interface?

Yes.When I block Interface for Home Zone ,it works,But for Public(Internet) Zone not working. :-\
