Hi All,

First, thanks for your help.

I finally found the issue...

I was pinging indefinitely a host to check barring.

Apparently, UDP & TCP are really blocked right after the pfctl -k, 
but ICMP ping (a ping -t from Windoze) keeps working.

Whatever I attempted to do, I did not succeeded setting up a real 
barring on all ports & protocols.

I must now check some other weird protocols as AH/ESP to ensure the 
HotSpot really bars properly traffic.
