Description

This seems to be a bug for some time now.It suppose to be fixed in VirtualBox 3.0.6 (released 2009-09-09) but this seems not to be the case(after trying 3.0.6 version).FreeBSD Guest can't see any multicast traffic in bridge mode sing any intel adapter (e1000) in 3.1.4 either.

Having the same problem. Under some circumstances neither Windows (host system) nor Gentoo linux (guest system) receive multicast packets (e.g. IGMP join).

I have a Windows machine (A) that connects to the WAN through the other Windows machine (B) which has VirtualBox with Gentoo installed on it. Gentoo acts as a router. It uses VirtualBox' bridging (e1000) for two real LAN ethernet interfaces: one for WAN, one for LAN.

Machine (A) starts VideoLAN Client to get IP-TV. VideoLAN sends IGMP packet to multicast address (it could be sniffed by Wireshark on this machine (A)). But this packet does not reach Machine B (router). Wireshark on Windows (B) and tcpdump on Gentoo (VirtualBox) show that there are no IGMP packets at all.

To fix this I do one very simple action: I stop my VirtualBox and start it again. This thing helps endeed - everything works fine after that.

So, at least a kind of instable behaviour take place here. Do not know - VirtualBox problem or Windows one...?
