problem with opening ports using iptables

hi list, i recently switched from personal-firewall to a self-made firewall script cause i want to share some ports (e.g. www) to the outside world. i decided to filter those ports and simply drop all other packets. to filter out the packets i use some code like this: IPTABLES -N www IPTABLES -A www -j ACCEPT IPTABLES -I INPUT -p tcp -m state --state NEW -i $INET_DEV --dport 80 -j www IPTABLES -I OUTPUT -p tcp -m state --state NEW -o $INET_DEV --dport 80 -j www but it doesn't work. other outside clients say my servers port 80 is opened but they don't recieve anything when accessing it. from the internal lan all things work fine. does anyone know whats wrong? thx in advance [LAN-Power.net] Tobias Breckle
