http://serverfault.com – I have a linux box with two NIC cards: eth0 and eth1. In one card i have 3 public IP: eth0 = 10.10.10.1 eth0:1= 10.10.10.2 eth0:2= 10.10.10.3 In the other card I have one local IP eth1 = 192.9.200.1 I want to redirect all the wan traffic for 10.10.10.2 to the LAN 192.9.200.2 and the same for 10.10.10.3 to 192.9.200.3 I have tried with this rule but doesn't work iptables -t nat -A PREROUTING -i eth0 -d 10.10.10.2 -j DNAT --to-destination 192.9.200.2 iptables -t nat -A PREROUTING -i eth0 -d 10.10.10.3 -j DNAT --to-destination 192.9.200.3 IP forward is enabled in /etc/sysctl.conf (HowTos)
