Vagrant does not assign correct gateway

I have created with Vagrant a brand new VM running Ubuntu 12.04 Since I need to access the VM always at the same IP address I have assigned to it a MAC address and set my DHCP in order to assign the same IP to the machine with that MAC.

My VagrantFile looks like

Vagrant::Config.run do |config|
  config.vm.box = "ubuntu-vm"
  config.vm.box_url = "http://files.vagrantup.com/precise32.box"
  config.vm.network :bridged, :bridge =>  "BGigabit Ethernet", :mac => "080027234567"
end

The VM is correctly created and the same IP assigned every time I boot it up. However, the Gateway is not properly configured.

Here my ifconfig

eth0      Link encap:Ethernet  HWaddr 08:00:27:12:96:98
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

          inet6 addr: ::1/128 Scope:Host

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

and here my routes

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         10.0.2.2        0.0.0.0         UG    0      0        0 eth0
default         10.0.2.2        0.0.0.0         UG    100    0        0 eth0
10.0.2.0        *               255.255.255.0   U     0      0        0 eth0
142.17.0.0      *               255.255.252.0   U     0      0        0 eth1

The eth1 gateway should be 142.17.0.1. Shouldn't the correct address be fetched from the DHCP?

Do I have to specify some extra params in my Vagrantfile to make it work?

THANKS.

You can only have one default gateway per system (not per interface). Your current gateway is set to 10.0.2.2 (probably the Vagrant master) over eth0 (Vagrant's management interface) – CyberJacob – 2013-11-07T08:29:17.913

I see, the first issue is why eth1 has 142.17.0.0 instead 142.17.0.1 that is the gateway in my DHCP?

Moreover, how can I set the last route as default? – Sig – 2013-11-07T08:33:26.617

You don't have a gateway set on eth1. 142.17.0.0 is the network address (covers 142.17.0.1 to 142.17.0.254) which is routed directly to eth1 without using a gateway. – CyberJacob – 2013-11-07T08:38:07.920

Thanks for you help. So, you mean everything seems fine to you. Correct? – Sig – 2013-11-07T08:59:53.197

Yes, it does. can you ping 8.8.8.8? – CyberJacob – 2013-11-07T19:13:55.863

From inside the VM I can ping it however I'm not able to ping any other machine in the network --- 142.17.1.4 ping statistics --- 24 packets transmitted, 0 received, 100% packet loss, time 23096ms – Sig – 2013-11-08T03:45:30.363
