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

  • Can we get the output of service iptables status (or iptables -n -L if you are not on Red Hat / Centos).

  • It's not clear what it is you're trying to do. What do you mean by "redirect all the wan traffic"?

If you don't have forwarding allow rule you might have to explicitly allow it using:

-A FORWARD -s 10.10.10.2 -d 192.9.200.2 -j ACCEPT
-A FORWARD -s 10.10.10.3 -d 192.9.200.2 -j ACCEPT
