Cannot redirect traffic to new IP with iptables on centOS


Hi, today I able to migrate some of the game servers to another server and needed some help to redirect the traffic from old ip to the new one.

SERVER1 1.1.1.1 ----- (internet ) -----> SERVER 2.2.2.2

I asume to use iptables to perform this, for that used this rule on my centOS box in the server1.

Quote:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -d 2.2.2.2 \
-p udp --dport 27015 -j SNAT --to 1.1.1.1


But the client cannot connect to the server from the old ip, the redirection don't started.

You need to use PREROUTING to redirect incoming traffic.

Here is a tutorial for doing the same thing: http://www.debuntu.org/how-to-redire...using-iptables
