You need to use the module "multiport" eg: iptables -t filter -A INPUT -p tcp -m multiport --dports 5000,8000 -j DROP Note that when you use -m multiport the module multiport is loaded and then you need to use --dports (not --dport). You will find this and more running: iptables -m multiport --help -- Maxwillian Miorim <miorimmax@gmail.com> ---- * Slackware 10.2/current * OpenBSD 3.9 * Debian SID Todo software em C deveria iniciar com um: #ifdef WIN32 printf(" Hey, what about a real OS?\n "); exit(1); #endif
