Hi!

I run on a Win7 host, with a Ubuntu 14 guest. Separate NIC for internet and the local net i got problem wiht.
IPs for guest 192.168.2.3. Other IP on my mini net 192.168.2.4.
When I do ping i only see ARP queries but no reponses. I can see these ARP requests both in the host and in the VM with wireshark.
In win7 I have disabled all features on the network settings for the adapter apart form the VirtualBoxNDIS6. I use BridgedAdapater in the VM settings.

Output:
arp -an

I have tried all different adapters though i didnt see this to be the problem. I am not 100% sure i have done everything correct so it would be nice with help.... Also i dont think it can be a firewall issue, as the requests are outgoing.
The device connected to this dedicated NIC works fine with other devices running with Native Ubuntu installation.

If you can send and receive then the NIC hardware is working. That is all that VirtualBox is responsible for. Network protocols, addressing, routing etc are not within the remit of the hardware, virtual or not.

You should not be "trying different adapters", you should stick to the hardware selected by the OS template, as that is what the guest OS has drivers for.

Yes, i have my target NIC of course i want to run, this was more for trouble shooting purposes. It is still not clear to me where the packets are discarded.
