In Ubuntu (client) manually configure the network adapter to be in the same subnet as the 'VirtualBox Host-Only Network' on the host and set the host ip as gateway/dns. This adapter is then shared with VirtualBox Host-Only Network via the rightclick - properties - internet connection sharing dialog. (Filesharing and all protocolls but IPv4 deactivated)

In Virtual Box set the adapter to Host-Only NetworkĬonnection established with OpenVPN GUI on TAP-Win32 Adapter V9.

Bridging over the VPN connection and running all attacks from inside the VM would solve that problem.Īny idea why the host can use this interface, but the VM can't? I want to be able to run active attacks (ARP spoofing, nmap, Nessus scans) in the sandbox environment without risking the traffic accidentally going over the university network and getting my internet access revoked. I want the virtual machine to bridge over the VPN connection, because our IT office has very strict policies about what you can and can't do on the network. It's like OpenVPN is filtering out packets from the MAC address it doesn't recognize. My host (Windows 7 Ultimate) connects to the VPN fine and is assigned an IP through DHCP, but for some reason the VM can't do the same thing, and I'm not sure why. The VPN is is hosted by the cybersecurity club at my university, and connects to a sandboxed LAN designed for penetration testing against various servers that the club has built. I'm trying to configure a virtual machine (VirtualBox guest running Backtrack 4) with a bridged adapter over a VPN connection.
