You need the local IP of Ubuntu. To get this type <code>ifconfig</code> in the terminal.

I've had success using NAT with virtualbox, after you get the machine's ip, type it with the 3000 port from the VM and you should be able to access it.

The answer is yes there is a simple way to do it. I am using VirtualBox on OS X Mountain Lion, but I suspect it will work the same for Ubuntu.

<ol>
<li>You don't need to use bridged mode, NAT works fine.</li>
<li>Just use the IP address of your host machine. e.g. <code>192.168.xxx.xxx:3000</code> </li>
<li>As an alternative, you can use <code>ipconfig /all</code> on your virtual machine in the command prompt (use windows search / find (windows+f) and search for 'cmd') Look for <code>Default Gateway</code> and use that IP. In my case it is <code>10.0.2.2</code> so <code>10.0.2.2:3000</code> works</li>
</ol>

If you're running rails in development mode, it comes with <code>webrick</code> by default which has access restricted just to localhost.
You could use something like <code>thin</code> in dev, which allows access from another machines.

I am currently running Rails 3.2.3 server on a laptop running Ubuntu 12.04 and would like to access it via VirtualBox (ver 4.1.16) from a WinXP (SP3) VM, which is also running on the laptop. Tried using bridged networking instead of NAT but end up with a refused connection in Firefox (ver 13). Firefox displays an error page which includes the following:

<blockquote>
 Unable to connect.
 
 Firefox can't establish a connection to the server at localhost:3000.
</blockquote>

Is there a straightforward way to access the Rails server from VirtualBox remotely? Not sure if Vagrant will resolve the issue since it is designed to work the other way around (from the host OS to the VM). Would be good to access the Rails server remotely as it means testing can be easily done with Internet Explorer (using ver 8) on a single PC on demand.
