Hi 

I wonder if any body can help me ?

I've got 2 Redhat 9 Linux Servers purely running iptables and only using the NAT function

I want to load balance over two boxes, I want to send traffic out the one box and SNAT 57.24.224.242, 
and return traffic to return to the second box and DNAT to 172.20.128.121 

If I send traffic over the one box and receive on the same box it works, but when I split the traffic it doesn't work !

the rules are as follows 

Box1 
iptables -t nat -A POSTROUTING -o eth1 -s 172.20.128.121 -j SNAT --to 57.24.224.242

Box2 
iptables -t nat -A PREROUTING -i eth1 -d 57.24.224.242 -j DNAT --to 172.20.128.121

Thanks
