vagrant should be able to forward tcp and udp on the same port number

[hdorio]

try this

Vagrant::Config.run do |config|
  config.vm.box = "base"
  config.vm.forward_port 5000, 5000, { :name => "port1"}
  config.vm.forward_port 5000, 5000, { :name => "port2", :protocol => "udp" }
end

vagrant up

[default] VM already created. Booting if it's not already running...
[default] Clearing any previously set forwarded ports...
[default] Forwarding ports...
[default] -- 22 => 2222 (adapter 1)
[default] -- 5000 => 5000 (adapter 1)
[default] Exporting NFS shared folders...
...

only one port is forwarded

I'm just post same issue than I see your post...

Has this reappeared in the new version?

Vagrantfile:

(10000..12000).each do |port|
  config.vm.forward_port port, port, protocol: 'tcp'
  config.vm.forward_port port, port, protocol: 'udp'
end

Error:

There are errors in the configuration of this machine. Please fix
the following errors and try again:

vm:
* Forwarded port '10000' (host port) is declared multiple times

The problem reappears with vagrant 1.2.7. If I want to forward both udp and tcp port 53 using the following configuration

  config.vm.network :forwarded_port, guest: 53, host: 53000, protocol: 'tcp'
  config.vm.network :forwarded_port, guest: 53, host: 53000, protocol: 'udp'

then only the udp-port gets forwarded. The configuration for the tcp-port-forwarding is completely ignored.

The problem is in plugins/providers/virtualbox/util/compile_forwarded_ports.rb where the host_port is used as a key for the hash containing the forwarded-port-configurations. A fix similar to hdorio's fix 76c9f67 should work though.
