VirtualBox: ping gives "DUP!" with Bridged wifi interface
I'm running VirtualBox 4.1.8 on Ubuntu 64-bit, which is connected to the the network via wireless adapter WLAN0.
I'm running another Ubuntu as a VM on VirtualBox with "Bridged Adapter" via WLAN0, and it has some network problems:
1) ping results in "(DUP!)" messages as seen below
2) the Ubuntu guest does get a public IPv6 address from the modem, but IPv6 doesn't work
When I switch the host system to fixed ethernet and disable wifi, the problem is gone: ping works normal, IPv6 works.
Problem seems related to https://forums.virtualbox.org/viewtopic.php?f=7&t=45886 which has no solution.
Any tips?

Re: VirtualBox: ping gives "DUP!" with Bridged wifi interface
I have the exact same problem , the Host system is ubuntu 11.10 and the guest is ubuntu server 10.04 .!
it was running fine before one week ago , but today I saw the error and the internet inside the VM is really slow
Re: VirtualBox: ping gives "DUP!" with Bridged wifi interface
FWIW:
The real problem for me is that IPv6 is half / not working: The guest does get an IPv6 address from the router/modem on the LAN, but IPv6 is not working. See below.
