I'm working with vagrant and I'm trying to use it as a printing server. I installed cups.

Internally everything works just fine. I can even make a quick curl to my localhost:631 (cups port inside my vagrant) and there's everything.

The thing is I can't access it in any way I try from the host machine.

Obviously I forwarded the port and I've tried with several ports. I've also tried with Debian squeeze and Ubuntu 12.04. Here is my current Vagrantfile

Vagrant.configure("2") do |config|                                              
  config.vm.box = "guruDebian"
  config.vm.network :forwarded_port, guest: 80, host: 8080
  config.vm.network :forwarded_port, guest: 631, host: 6363   ## HERE IS CUPS           
end

Any ideas? ... I'll upload any file if necessary.
