Redirect traffic to a new IP address

First make sure you enable forwarding

sysctl net.ipv4.ip_forward=1

Next issue the iptables rules for the port you want to redirect.

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 69.174.244.190:80

Next we will masquerade the traffic

iptables -t nat -A POSTROUTING -j MASQUERADE
