    Hey

    I was wondering how can i add multiple ip addresses to ip tables instead of having to block one by one.

    Thanks

    I don't know of any extension that supports multiple comma-separated values for ip addresses (there is one for ports), but you have 2 options which might help.

    You can either specify a network address in various forms (such as 192.168.0.0/24 or 10.0.0.0/255.0.0.0) or use the iprange extension. You can use the iprange extension like this:

    iptables -I INPUT -m iprange --src-range 192.168.0.100-192.168.0.200 -p tcp --dport 22 -j LOG
