Vagrant: Port forwarding not working (no service iptables started, provisioned by salt)

This is my Vagrantfile.

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

config.vm.box = "precise32"
config.vm.box_url = "http://files.vagrantup.com/precise32.box"

config.vm.hostname = "myapp.dev"

config.vm.network :forwarded_port, guest: 9000, host: 9000, auto_correct: true

config.vm.network :forwarded_port, guest: 8983, host: 8983, auto_correct: true

config.vm.synced_folder "salt/roots/", "/srv/"
config.vm.provision :salt do |salt| 

salt.minion_config = "salt/minion"                                         
salt.run_highstate = true                                                  
salt.install-type = "daily"                                                
salt.verbose = true

end
config.vm.provider :virtualbox do |v| 

v.customize ["modifyvm", :id, "--memory", 1024]

end

end

From inside the vagrant machine, curl -L localhost:9000|wc returns a lot of words, lines and whatnot, and the answer is a HTTP proper response.

From outside the vagrant machine, curl -L localhost:9000|wc returns 0 lines (and the others), and curl -L localhost:9000 returns the message Connection reset by peer.

The service iptables is running neither in my local machine, nor in my virtual machine.

the services that are running in my virtual vagrant machine are

  • [ + ] apache2
  • [ + ] apparmor
  • [ + ] memcached
  • [ + ] ntp
  • [ + ] rabbitmq-server
  • [ + ] ssh
  • [ + ] supervisor (i've only listed the ones with '+' status)

The services running on my local machine are

  • [ + ] apparmor
  • [ + ] redis-server
  • [ + ] saned

If any more info is required, i'll supply it.

[EDIT] I've also tried netcat-ing

on the virtual machine:

$ nc -l 8978

on the local machine

>$ nc localhost 8978
>$

At this point the connection initiated from the local machine to the virtual machine is closed, but the virtual machine keeps listening)

HOWEVER, when i start listening with nc -l 65530 on the local machine, and connect to it with nc 65530, i can send packets.

Got it:

VirtualBox was caussing the issue:

Apparently i had another box started up, which was also listening on port 9000. When i started up my box, i received a message that instead of forwarding from 9000 -> 9000, it was forwarding from 2201 -> 9000. I simply turned off the other box.

This was happening because of the auto_correct parameter set in the Vagrantfile.
