I've set up CentOS 6 on a vagrant box with a private network IP. I can ssh into the box using the IP, so that is working. However, I get a Connection refused on port 80 when curl'ing it. There's a very basic nginx serving up its default welcome page inside. Curling it from inside the box works.

Vagrant.configure("2") do |config|
  config.vm.box = "Centos-6.3-minimal"
  config.vm.box_url = "https://dl.dropbox.com/u/7225008/Vagrant/CentOS-6.3-x86_64-minimal.box"

  config.vm.network :private_network, ip: "192.168.33.44"
  config.vm.hostname = "local.example.com"

  config.vm.provider :virtualbox do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end
end

Here are some things I have tried:

• Changing to port forwarding 80 -> 8080. Curling on localhost:8080 just hangs there.
• Trying another IP address. No difference.
• Opening a python -m SimpleHTTPServer on the server that is known to listen on 0.0.0.0. Still getting Connection refused.

These things are known to work:

• SSHing in to the server using the given private network IP works.
• Curling from inside the box works.
• The same setup works on a real server.

I've got Guest Additions installed, but their versions are different on guest and host. That might be the problem. But then why does SSH work, and not port 80? This is the output when I do vagrant reload: https://gist.github.com/magnars/496e553f07ad5c770c54

Update

While this does not work:

config.vm.network :forwarded_port, guest: 80, host: 8080

This does:

ssh -f deploy@local.example.com -L 8080:127.0.0.1:80 -N

Any ideas?
