Unable to connect to Vagrant private network from host

Question

I have a vagrant virtual box up and running. So far I have been unable to connect to the web server. here is the start up:

on my host console, ip addr show yields:

    link/ether 0a:00:27:00:00:01 brd ff:ff:ff:ff:ff:ff

on the guest it yields:

vagrant@vvv:~$ ip addr show

    inet 192.168.50.4/24 brd 192.168.50.255 scope global eth1

For now, all I want to do is access the web server on the virtual machine, whatever way works. I have tried a variety of things, just shooting in the dark. I would be happy to provide any specific info. Any help or suggestions would be greatly appreciated

Answer 1

Based on the output provided, the box has 2 network interfaces, 1 is the default NAT and the other private - ask you said.

The reason why you are not able to access the web site hosted within the VM thru the private interface: it could be that host eth0 or wlan0 IP address is not in the same network as the private interface -> 192.168.50.4/24 and there is no route.

To access the the site hosted by the web server within the guest, you have the following options:

1. NAT port forwarding

Forward the web port, e.g. 80 to host's 8080 (you can't use 80 because it is a privileged port on *NIX). Add the following

Vagrant.configure("2") do |config|
  config.vm.network "forwarded_port", guest: 80, host: 8080,
    auto_correct: true
end

NOTE: auto_correct will resolve port conflicts if the port on host is already in use.

DO a vagrant reload and you'll be able to access the site via http://localhost:8080/

2. Public Network (VirtualBox Bridged networking)

Add a public network interface

Vagrant.configure("2") do |config|
  config.vm.network "public_network"
end

Get the IP of VM after it is up and running, port forwarding does NOT apply to bridged networking. So you'll be accessing the site by using http://IP_ADDR, if within the VM it binds to 80, otherwise specify the port.
