I blocked one IP address so that the IP can't connect to my webserver. Now I want to unblock this IP address. How can I do this?
To unblock your blacklisted IP address, you can use the below-given command.
$ iptables -D INPUT -s 10.0.0.124 -p tcp --destination-port 80 -j DROP
$ iptables-save > /etc/sysconfig/iptables
Hope this will help.
