Just ran the “Common Port” test using Gibson Research Corporation at GRC | ShieldsUP! — Internet Vulnerability Profiling , but failed with the following result which is shown as below.
I am using CIS with Windows XP Home Edition behind ASUS WL-520GU router; and did not modify or change any rule in CIS nor router.
Does anyone have the same experience? Any help or suggest is highly appreciated, thanks a lot!
