Hi people, I wrote some rules in my firewal like bellow. When I started it blocked my all connections, and I realised that ( <#iptables -P INPUT DROP #iptables -P OUTPUT DROP #iptables -P FORWARD DROP ) blocking everything.So I put in comment. I am confused because this rule is at beggining of firewal and I do not understand why rules that comes after are not implemented. I want to block all traffic first and theh allow specified trafic. Please I need your opinions, I read many sources and I understand what above rules means, but I can not understand why rules after does not working. Regards PS : Links and other resources are welcome too Thanks Elvir Kuric iptables -F iptables -t nat -F iptables -t mangle -F iptables -X iptables -t nat -X iptables -t mangle -X #iptables -P INPUT DROP #iptables -P OUTPUT DROP #iptables -P FORWARD DROP iptables -A INPUT -s 127.0.0.1/255.0.0.0 -j ACCEPT iptables -A OUTPUT -d 127.0.0.1/255.0.0.0 -j ACCEPT iptables -A INPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE #iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to-source ip_adresa iptables -A OUTPUT -p tcp --dport 22 -j ACCEPT __________________________________________________ Do You Yahoo!?
