Is there a way to forward a range of ports using vagrant 1.2.1 or higher? I know that you can forward any number of ports individually by using
config.vm.forward_port 80, 4567
Or, is the answer simply don't use vagrant to do such a thing?

Does this help? docs.vagrantup.com/v2/networking/forwarded_ports.html– dawudJun 29, 2013 at 10:44

Not exactly. Wanted to know if you can specify a range of ports to be open, rather than one at a time. Perhaps I'll contact the author directly.– AcornJun 30, 2013 at 12:19

5Since the Vagrantfile is just a Ruby script you might be able to write a for loop that executes config.vm.forward_port for every port you want. I'm not fluent in Ruby, so I can't really help you with code.– LasarJul 8, 2013 at 12:27

If anyone needs an example of how to do the loop in your Vagrantfile here it is:
for i in 64000..65535
config.vm.network :forwarded_port, guest: i, host: i
end
The above loop will forward all ports between 64000 and 65535 to the exact same port on the guest (note that 64000 and 65535 are inclusive).

2On my computer vagrant was a bit long to map 1000 ports. Unless you really need so many mapped ports, you should map 50 ports.– AntoineAug 26, 2015 at 12:17

@Antoine yes I've noticed that it is very slow as well. I normally end up just using 10 to 20 for development boxes. Sep 17, 2015 at 2:17

Extremely slow to check used ports on windows, errors out once the command line limitation kicks in. Mar 2, 2018 at 11:25

The 'for' examples above are correct for doing an inclusive range. If you would like to forward a set of specific ports, you need to use the Ruby .each operator.
The variables can go inside or outside of the main Vagrant.configure loop.
UDP_PORTS_LIST={
"5000" => 5000, # Some service
}
TCP_PORTS_LIST={
"5900" => 5900, # VNC
}
The loops need to go inside the Vagrant.configure block for the VM you want to map them for (remember you can have multiple VMs in a single Vagrantfile).
UDP_PORTS_LIST.each do |guest, host|
config.vm.network "forwarded_port", guest: "#{guest}", host: "#{host}", protocol: "udp"
end
TCP_PORTS_LIST.each do |guest, host|
config.vm.network "forwarded_port", guest: "#{guest}", host: "#{host}", protocol: "tcp"
end
