Sorry for the delay in answering your question ...

Well, it's because some users inside the internal networks under my 
administration visit http://www.grc.com/ and run the Shields Up! to see the 
open ports in the gateways and they see the port 0 open. That was the reason 
to apply the rule.

Jorge.
