VirtualBox with Ubuntu Server guest can't ping outside
- by Danidan
Here's my situation:
an Ubuntu 12.04 Host running VirtualBox;
two guest VMs running Ubuntu Server 12.04
home network, so my Host pc has a wireless connection to the router of my ISP.
My problem is in one of the virtual machines: it has 3 NICs, one in NAT mode and the others in Host Only mode. My purpose is to use eth0 (NAT) for Internet access and eth1, eth2 (Host Only) for management of internal virtual network (eth1 uses a VBoxNet with this IP 192.168.69.254).
Whenever I try to $ping 8.8.8.8 I get Destination Host Unreachable.
While if I $ping 192.168.69.10, that is the IP of the other VM, it works.
I can't also ping my Host nor my router
My /etc/network/interfaces file is:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet static
address 192.168.69.1
netmask 255.255.255.0
auto eth2
iface ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFASE promisc off
down ifconfig $IFACE down
$route -n returns:
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.0.2.2 0.0.0.0 UG 100 0 0 eth0
10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.69.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0
Forgetting for now what eth2 needs to do and its setup, why I can't go outside the Host box?
What can I do to help you helping me? :-)
