Hello, I have an iptables firewall/router with 2 NICS and one alias setup. What I am trying to accomplish is route traffic coming in off the alias to an internal server ip address. All normal web traffic goes through eth1 and out eth0. eth0 = external interface 69.21.X.1 eth0:1 external interface 69.21.X.2 eth1 = internal interface 192.168.1.1 My iptables script looks like this.... echo "1" > /proc/sys/net/ipv4/ip_forward iptables -A INPUT -i eth1 -j ACCEPT iptables -A INPUT -i eth0:1 -j ACCEPT iptables -A OUTPUT -o eth0:1 -j ACCEPT iptables -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -i eth0 -m state --state INVALID -j DROP iptables -A INPUT -p tcp --syn -j DROP iptables -t nat -A PREROUTING -p tcp -i eth0:1 -d 69.21.103.132 --dport 80 -j DNAT --to-destination 192.168.1.3:80 iptables -A FORWARD -p tcp -d 192.168.1.3 --dport 80 -j ACCEPT iptables -t nat -A POSTROUTING -s 69.21.X.2 -j SNAT --to-source 192.168.1.X Having a hard time figuring out what Im doing wrong with this. Any help would be greatly appreciated. -- Bo Lynch -- 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
