Hi all I would like to write this sentence in iptables rule: "REJECT everything having port #443 (httpS) as destination except if the IP address that query it are one of 192.168.0.18 or 192.168.0.50" I'd like to forbid httpS/443 traffic except for those two IP addresses. I made: $IPT -t nat -A PREROUTING ! --source 192.168.0.50 \ -p tcp --dport 443 -j REJECT and $IPT -t nat -A PREROUTING --source ! 192.168.0.50 \ -p tcp --dport 443 -j REJECT But they are all bad syntax. Would you please help me to find my mistake? I'm running iptables v1.4.0 -- Chef de projet chez Vectoris Phone: +261 33 11 207 36 System: xUbuntu 8.10 with almost all from package install http://www.google.com/search?q=mihamina+rakotomandimby -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
