How to block an IP address?
Solution 1:
Finally, I found a solution by using PF.
(1) edit PF configuration
sudo vim /etc/pf.conf
Append the following line to the file:
block drop from any to <IP Address>
For example: block drop from any to 8.8.8.8
(2) Load the config by running
sudo pfctl -f /etc/pf.conf
(3) Enable PF by running:
sudo pfctl -e
(*) If you want to disable PF, run:
sudo pfctl -d
