CF in Block All mode - but I can connect to other computers

Hello,

What the …
I set CF to Block All mode. Yes, I do not have Internet connections, BUT I can browse computers in local network (not 198...* network. Public IPs). The same happening when I put Block All rule on first place in Global rules. I do not have any “Trusted Network”, except 127.0.0.1/255.0.0.0
So, what the problem ? (:SAD)
I have last version of CF installed
