Open the local security settings, click "IP Security Policy, on the local machine"-- > create IP security policy-> next-> write a name casually, such as enter block, and then click on the next step. The cue point is, until it is finished, a policy called "block" has been created.

Click "IP Security Policy on Local Machine"-- > manage IP filter tables and filter actions-> add-> name add 75.156.25 (to identify the best IP segment)-> add-> next-> Source address Select a specific IP subnet IP enter the subnet mask of 75.156.25.0 to change to 255.255.255.0-- > next-> destination address Select my IP address-> next-> Protocol type is any-> next-> complete all shutdown.
