title: Vagrant won't forward ONLY port 80
body: <p>I have port forwarding set up for vagrant</p>
  
  <pre><code>Vagrant.configure("2") do |config|
    config.vm.box = "centOS"
    config.vm.network :forwarded_port, guest: 80, host: 80
    config.vm.network :forwarded_port, guest: 8443, host: 8443
    config.vm.network :forwarded_port, guest: 8443, host: 9443
    config.vm.network :forwarded_port, guest: 8445, host: 8445
    config.vm.network :forwarded_port, guest: 8000, host: 8000 
    config.vm.hostname = "www.vagrant.com"
  end
  </code></pre>
  
  <p>Port 80 is open from my vagrant virtual box</p>
  
  <pre><code>[vagrant@www ~]$ nmap -sT 0.0.0.0 -p 80 
  
  Starting Nmap 5.51 ( http://nmap.org ) at 2013-07-02 22:25 UTC
  Nmap scan report for 0.0.0.0
  Host is up (0.000063s latency).
  PORT   STATE SERVICE
  80/tcp open  http
  </code></pre>
  
  <p>But it is closed from my host machine</p>
  
  <pre><code>Ben-Fischer:~ bfischer$ nmap -sT 0.0.0.0 -p 80 
  
  Starting Nmap 6.25 ( http://nmap.org ) at 2013-07-02 17:38 CDT
  Nmap scan report for 0.0.0.0
  Host is up (0.000086s latency).
  PORT   STATE  SERVICE
  80/tcp closed http
  </code></pre>
  
  <p>Nothing else is listening on port 80 on my host machine</p>
  
  <pre><code>Ben-Fischer:~ bfischer$ sudo lsof -n -i4TCP:80 | grep LISTEN
  [no output]
  </code></pre>
  
  <p>Iptables are off and so is my mac firewall</p>
  
  <pre><code>[vagrant@www ~]$ sudo service iptables stop
  </code></pre>
  
  <p>And all of the other forwarded ports work fine (8443,9443,8445,8000) </p>
  
  <p>The box is an image from vagrant, centOS 6.3 with chef.</p>
  
  <p>So... why can't I connect to port 80 from my local machine?</p>
