DNAT Issue

Asked by PEI_IT in IP Tables/IP Chains, Linux Network Security

Kia ora Experts!
I have a working set of iptables rules.  My input, output, forward and postrouting rules work well.  However, when I try to port forward with DNAT it fails.  

The rule that I am testing is: iptables -t nat -A PREROUTING -p tcp -d 124.197.14.110 --dport 80 -i eth1 -j DNAT --to-destination 10.0.0.53.

Eventually I need DNAT rules to forward http, MS SQL, and SMTP.
