Hi, We've been under attack recently and I would like to block IPs with iptables next time. I tried to add IPs but I get the following message, anyone who can help? [quote:7ce9b8283e]iptables v1.2.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.[/quote:7ce9b8283e] Thank you.
