I want to have UDP load balancer, which seems to achieved from iptables from this post
I run this command which resulted in error as shown below.
iptables -t nat -A PREROUTING -p udp -i em1 --dport 9998 --mode nth --every 2 --packet 0 -j DNAT --to-destination xx.xx.xx.xx:9998
iptables v1.4.21: unknown option "--mode"
I have also installed the ipset package,
yum install ipset
How to install the iptables-module which has --mode option ?, from the man pages, seems like i need to install statistic module but could not find out the tar/rpm file.
