I just want to clarify some doubts regarding some built in firewall rules

HI ,

I have a few clarifications needed on SEP default firewall rules

1) Why is LLMNR protcol allowed for IPV6 by default and blocked for IPV4

2) In Applications column in firewall rules  : Whats the differnce between a  ( * and any )

3) By default SSDP , WSD from external computers are blocked ?? Why is that

4) Allow USB over IEEE and Allow Wireless EAOPOL are blocked .What is the benefit of doing this.
