Hiii, Can someone tell me why these rules will only casue errors "sometimes"? I ran my script before and it worked fine. But then i added a few more log polocies and drop rules and then i get errors. I know its these rules casue when i # commented them out the script it ran properly again and it happened before but it fixed itself somehow. Here are the rules that are casue the error: iptables -A OUPUT -o eth0 -p tcp \ -s eth0 --sport 1024:65535 \ --dport 80 -j ACCEPT iptables -A INPUT -i eth0 -p tcp \ --sport 80 \ -d eth0 --dport 1024:65535 -j ACCEPT iptables -A INPUT -i eth0 -p udp \ -s 122.xx.xxx.xx --sport 67 \ --dport 68 -j ACCEPT iptables -A OUTPUT -o eth0 -p udp \ -s eth0 --sport 68 \ -d 122.xx.xxx.xx --dport 67 -j ACCEPT Here the error i get: iptables v1.2.7a: host/network `eth0' not found Try iptables `iptables -h' or `iptables --help for more infomation' iptables v1.2.7a: host/network `eth0' not found Try iptables `iptables -h' or `iptables --help for more infomation' iptables v1.2.7a: host/network `eth0' not found Try iptables `iptables -h' or `iptables --help for more infomation' Here are the rules i added and they work fine when i comment out the above rules! iptables -t nat --policy PREROUTING -j DROP iptables -t nat --policy OUPUT -j DROP iptables -t nat --policy POSTROUTING -j DROP how can i fix this? thanks guys! i have a dynamic ip address and i cant get pump to work thats why i using eth0 instaead of an IP adress! __________________________________________________ Do you Yahoo!?
