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.
