[网络协议]Block IP address in Mac

最近一直试着抓一些app的包，无奈受制于很多app不走HTTP, 而是基于其他协议，就想着能不能封掉tcp协议的地址，让app强制走http。 在Mac上，可以尝试封掉某个IP地址：

1> go to /etc/pf.conf

sudo vim /etc/pf.conf

2> add ip address

block drop from any to [IP ADDRESS]

Example ### block IP address

block drop from any to 192.168.1.1 , 注意一点要在最后一行添加

3. quit VIM and load the config file

pfctl -E

e is for enabling the packet filter

f is for loading the rules contains in the file

应该就可以了。

如果要取消：pfctl -d
