How to redirect traffic from one IP to another IP


/sbin/iptables -t nat -A PREROUTING -p icmp -d 10.106.210.176 -j DNAT --to-destination 10.20.1.2


To view whatever is configured:

/sbin/iptables -t nat -vnL --line-number  (with nat)
/sbin/iptables -vnL --line-number           (without nat)



To Delete/remove :
/sbin/iptables -D FORWARD 1   (without nat and 'FORWARD' is the policy, replace accordingly from whatever is listed from above command output)

another example to delete with nat:
/sbin/iptables -t nat -D PREROUTING 1   (here 1, 2 ..3 are the line-numbers which will get listed from view command)
