VirtualBox: Host and NAT conflict only?


Wikowitz

I have a Windows XP w/ SP2 (guest additions installed) configured with 2 network cards.

Network Card 1:  Host-only
    IP:   10.0.2.15       (static)
    Mask: 255.255.255.0
    DG:   10.0.2.1        (vboxnet0)

Network Card 2:  NAT
    IP:   10.0.3.15       (auto)
    Mask: 255.255.255.0
    DG:   10.0.3.2

Host OS - Linux (192.168.100.102)

ping 10.0.2.15  ... OK!

Windows XP:

ping 192.168.100.102   ... OK!
ping google.com        ... FAIL! (time out)

However, when I disable network card 1 from Windows' control panel, I can ping google.com. Virtual Box 4.2.18

Any ideas?

Most likely, you have a routing table specifying that your default gateway is on the host-only network, not the main connection. Which interface is selected as the default gateway at boot time depends on the changes in boot, and the same IF does not always come first. You can peruse the routing table with

route print 

You can add 10.0.3.2 as the default gateway by:

route delete 0.0.0.0 mask 0.0.0.0 10.0.2.1
route add    0.0.0.0 mask 0.0.0.0 10.0.3.2

Of course, the first command will delete the current default gateway, and the second command will delete the new default gateway. If you plan to make this permanent,

route -p add 0.0.0.0 mask 0.0.0.0 10.0.3.2
