guest <--- host "host - only" promiscuous mode doesn't work

Reported by: testa Owned by:
Component: network Version: VirtualBox 4.1.12
Keywords: host-only promiscuous allow-all Cc:
Guest type: Linux Host type: Linux

Description

Host can't see the traffic between two VM's with their nics configured with conntection:'host-only' promiscuous:'allow all'

Expected behaviour: see the traffic between two VM's with their nics configured in 'host-only' promiscuous 'allow all' mode.

Test: Generate a 'host only' network Build three linux guests "G1, G2"

Configure their nic's with:

Connected to: 'host only' Promiscuous mode: 'allow all' Cable connected: ticked.

Launch both Guests. Configure host's virtual nic. Configure guests' vrtual nics.

pings: G1 <-> G2 OK G1 <-> H OK G2 <-> H OK

open a wireshark in G2 and start it open a wireshark in the host and start it in the virtual NIC.

ping: G1 <--> H : sniffed by G2 G1 <--> G2: NOT sniffed by H

Replace host with a corretly configured guest (G3) G1 <--> G3: sniffed by G2

I've found some forum posts with reporting the same issue.

I'm also experiencing this issue. Is anyone at Oracle working on this or is ticket11264 not a bug but a feature ? My following question is ofcourse, when a solution would be available ?

If all the replies are negative, has anyone found a workaround for this bug ?
