Source or destination ? Coming in to your firewall, or going through it ? If it's a specific source coming in to your machine, try: iptables -A INPUT -s 11.22.33.44 -j DROP If it's a specific source going through your firewall to somewhere else, try: iptables -A FORWARD -s 11.22.33.44 -j DROP If it's a specific destination you want to stop people going to through the firewall, try: iptables -A FORWARD -d 11.22.33.44 -j DROP Hope this helps, Antony.
