I am trying to block one IP with iptables in my Ubuntu server 12.04.
The foreign IP is 188.8.131.52.dyna. You can take a look at the next image:
I have added this ip to iptables with the next command:
sudo iptables -A INPUT -s 184.108.40.206 -p tcp -j DROP sudo service iptables-persistent save sudo service iptables-persistent restart
However, when i run again the command
netstat -tap, this IP is not blocked.
How can I remove/block/delete this IP from my Ubuntu server?
