Hello,
I'm trying run an accesspoint on a linux guest under a linux host.
In my scenario I have wireless lan which have to be bridged over a specified vlan.
In my host configuration, I have multiple interfaces, each one associated with a specified vlan, so for example, the host eth0.4 is associated with the vlan 4. This part is tested work.
Giving this, I made a VirtualBox guest configuration where the guest interface eth1 is bridged with the host interface eth0.4 .
Testing this, it is also working, at least for normal traffic; where with normal traffic I mean that frames broadcast, multicast and unicast with destination address matching the guest interface flow as I expected.
About the wireless lan, this is realized using an USB dongle inserted in the host USB port and forwarded to the guest.
This also works as I expected.
My issue comes in when I bridge in the guest linux the wireless lan and the ethernet interface, and I expect to see flow unicast frames directed toward stations in the wireless lan from the ethernet interface.
It seems to me like if unicast traffic with destination mac address, different from the guest interface address, is filtered before it arrives to the interface.
Is anybody ever face a problem like this?
Does the guest configuration have any parameter to regulate this behaviour?
I would appreciate read any comment about this issue.
