I am trying to set up a set of guests in VirtualBox, such that each of them can access the Internet as well as be visible to each other and to the host. I also want the guests to have static IP addresses.
Here's the procedure that I have followed so far:
- Switch off the DHCP Server feature of the Host-Only network to be used in this setup
- Change the IP address assigned to the host to 192.168.56.254
- Create a guest machine with 2 networking interface cards (NIC)
- Configure the 1st NIC to use NAT
- Configure the 2nd NIC to use Hot-Only Networking
- Install the OS (Ubuntu Server 13.10) on each of them
- Update the OS
- Configure the networking as follows by editing /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet static
address 192.168.56.1
netmask 255.255.255.0
network 192.168.56.0
broadcast 192.168.56.255
gateway 192.168.56.254
dns-search cloudspace.local
dns-nameservers 8.8.8.8 8.8.4.4
- Save the file
- Reboot
When the guest boots up again, the Host-Only networking is working fine. The host/guest and guest/guest pairs of machines can ping each other, however the Internet isn't working as apt-get fails.
If I then issue a service networking restart command, the networking begins to work as it should.
What am I doing wrong?
I have tried switching the order in which the NICs appear in the /etc/network/interfaces file. I have also swapped the NAT/Host-Only Network around between the 2 NICs. Nothing worked.
The host is Windows 8.1 and the guest is Ubuntu Server 13.10. I have tried the same on Mac OS X with similar results.
I would greatly appreciate any help in this.
Update:
I have included the output from the following commands below, to help in diagnostics:
- cat /etc/network/interfaces
- ifconfig -a
- route -n
$ cat /etc/network/interfaces

$ route -n

0.0.0.0 192.168.56.254 0.0.0.0 UG 0 0 0 eth1

192.168.56.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
Update 2:
After I execute sudo service networking restart, the output from route -n becomes:
$ route -n

0.0.0.0 10.0.2.2 0.0.0.0 UG 0 0 0 eth0

So how do I ensure this configuration on boot?
