Just wondering is this true. As they literally has blocked installations of every major Firewall software in world to Windows 7 OS. and why I am suspecting such is because I am testing an Virtual machine connected Windows 7 with ESET Smart Security and this takes connections beneat firewall to servers: 65.54.89.xxx 184.108.40.206 199.7.xxx.xxx 207.46.xxx.xxx 213.155.158.xxx 213.199.xxx.xxx Wonder when do we need 3rd party hardware IP-Filters to be sure of protection or server box of some sort, if OS can do this straight forward why couldn't anyone else do this? Also would be interested on the 'locked' system service firewall rules. Why I cannot remove them as well?
