---

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

caged

// Start `node d3-server.js`
// Then visit http://localhost:1337/
//
var d3   = require('d3'),
    http = require('http')

http.createServer(function (req, res) {
  // Chrome automatically sends a requests for favicons
  // Looks like https://code.google.com/p/chromium/issues/detail?id=39402 isn't
  // fixed or this is a regression.
