NodeJS server not accessible from outside

Question

I deployed a nodejs server in Rackspace and can be accessed internally, like using:

curl http://127.0.0.1:8080

However, it can't be accessed from the outside (the internet) even if I do this:

iptables -A OUTPUT -p tcp  --dport 8080 -j ACCEPT
iptables -A INPUT -p tcp  --dport 8080 -j ACCEPT

Here is what my code looks like:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Simple server\n');
}).listen(8080, "0.0.0.0");
console.log('Server running at http://0.0.0.0:8080/');

Any ideas?

I think you should try not specifying an IP.

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Simple server\n');
}).listen(8080);
console.log('Server running at http://0.0.0.0:8080/');
