title: Can't connect to redis on vagrant machine
body: <p>I am setting up a dev environment that has two vagrant machines. One is a http server the other is a redis server. I cannot connect via port 6379 between the two machines. I also cannot connect to the vagrant machine from the host. I have set this type of configuration up in Centos but this is my first experiment with Ubuntu. Here are the Details, with private network addresses:</p>
  
  <p>Host: OSX Yosemite(192.168.33.1)</p>
  
  <p>Vagrant Machines: ubuntu1404-x64</p>
  
  <p>http(192.168.33.22)
  redis(192.168.33.20)</p>
  
  <pre><code>Redis conf:
  bind 0.0.0.0
  port 6379
  </code></pre>
  
  <p>On redis vagrant I am able to connect to redis with:</p>
  
  <pre><code>redis-cli -h 192.168.33.20
  </code></pre>
  
  <p>And I can connect to the host redis from the vagrant machine with:</p>
  
  <pre><code>redis-cli -h 192.168.33.1
  </code></pre>
  
  <p>But I cannot connect to the vagrant redis server remotely (from host or another vagrant machine)</p>
  
  <p>On the vagrant machine I get the following output:</p>
  
  <pre><code>$ sudo netstat -nlpt | grep 6379
  6:tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN          1004/redis-server 0
  </code></pre>
  
  <p>From the host machine I get the following:</p>
  
  <pre><code>$:nmap   -Pn -p 6379  192.168.33.20
  
  Starting Nmap 5.51 ( http://nmap.org ) at 2015-03-15 10:48 PDT
  Nmap scan report for 192.168.33.20
  Host is up.
  PORT     STATE    SERVICE
  6379/tcp filtered unknown
  
  Nmap done: 1 IP address (1 host up) scanned in 3.39 seconds
  </code></pre>
  
  <p>On the redis machine I have tried disabling the firewall with </p>
  
  <pre><code>sudo ufw disable
  </code></pre>
  
  <p>and enabling the firewall and adding (current state):</p>
  
  <pre><code>sudo ufw allow 6379
  </code></pre>
  
  <p>Now I get the following output on the redis guest:</p>
  
  <pre><code>$ sudo ufw status
  Status: active
  
  To                         Action      From
  --                         ------      ----
  6379                       ALLOW       Anywhere
  6379 (v6)                  ALLOW       Anywhere (v6)
  </code></pre>
  
  <p>But nothing has changed. I am still unable to reach the port from either the other vagrant machine or my host machine. Nmap still lists the port as "filtered".</p>
  
  <p>Edit: As mentioned in a comment below this code is a project I am taking over for and the Vagrantfile was created using something called pupphpet. The Vagrantfile is boilerplate, all the configuration comes from a yaml file. Here it the config for the redis guest:</p>
