Hi, Can you please check if the following rule is correct. The purpose of this rule is to allow only access to youtube from 15:00 to 18:00 iptables -A OUTPUT -p tcp --dport 80 -d 208.65.153.238 -m time --timestart 15:00 --timeend 18:00 -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -d 208.65.153.238 -j REJECT How can I modify the above rule to block a specific IP or MAC address from my internal network to access youtube at specific times? Thank you guys Have a nice day Danny -- 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
