Is it possible to block an IP starting with?
For example i want to block ALL IPs that starting with
188.67.
Is there a command or a way for that?
My problem:
I have a game server, and A person keeps accessing into with with a proxy server, all of his IPs are starting with 188.67.
What should I do?
You can use
sudo iptables -I INPUT -s 188.67/16 -j DROP
which will drop all packets from IP addresses from 188.67.0.0 to 188.67.255.255. If this works and you're happy with it then use
service iptables save
to write the new configuration to /etc/sysconfig/iptables.
Yes it is possible. But keep in mind that you will be blocking lots of other legitimate users who might visit your server from the 188.67 IP.
/sbin/iptables -I INPUT -s 188.67.0.0/16 -p tcp --dport 80 -j DROP
You can change the -p option depending on which protocol your server uses, and --dport for the port number on which the server is listening.
