Hi I try to build a firewall with iptables but there's something I don't understand. I set the default policy for all tables to DROP:
iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT DROP Then I allow to ping. # allow ping iptables -A INPUT -p ICMP --icmp-type echo-request -j ACCEPT iptables -A OUTPUT -p ICMP --icmp-type echo-reply -j ACCEPT Then I ping any machine. The system tells me "ping: sendmsg: Operation not allowed". Has someone got a clue why I can't ping even if I explicitly tell the firewall that pinging is allowed? Thanks for any help.
