Centos 6.4 Nodejs external not responding - linux

Question

I am new to ssh and Centos 6.4 and I want to run nodejs on port 80. But couldn't make it to work external.
When I type netstat -anp | grep 8080 I can see that my node listening.
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 7976/node
But it is not going external.
I tried to add settings to iptables and result is same again. It is not working.
[root#culturalinfluences ~]# iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
ACCEPT tcp -- anywhere anywhere tcp dpt:http
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:http /* node.js port */
ACCEPT tcp -- anywhere anywhere tcp dpt:http
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:webcache /* node.js port */
Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Here is my nodejs
var port = 8080;
app.listen(port, "0.0.0.0" ,function() {
console.log("Listening on " + port);
});
Thank you four understand cause I am really new into linux and its iptables system. I am sure people like me will search the same issue and I hope they will find answer from this question.
Thank you for your helps.

Answer 1

You have a
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
right before the "http" ports you're allowing, so those rules will never be reached. Move the REJECT all rule to the bottom of the list instead.
Additionally you may want to use -n on the iptables command line to make sure the port numbers are right and aren't 80 instead of 8080 for example.
