Broadcast Raw Packet problem between VBox VMs on diff. nodes

[kemosparc]

Hi,

I have a problem with broadcast packets.

I have 4 VMs running my OS (each 2 on a host) with bridged network, and my OS continuously sends broadcast packets every preset number of pits.

The problem is that each 2 VMs that are located on the same host can see the packets of each other.

I mean that the linux OS underneath does not let the broadcast packets go on to the network.

The packets are special packets with Ethernet type of my own (0x0333)

When I ping any of the machines they respond from anywhere on the network, also I can use a built in http server in my OS, so TCP traffic works well from anywhere on the LAN.

When I run tcpdump on any of the two hosts I can only see the broadcast packets of the VMs running on it.

Any ideas what might be the problem.

Thanks,
Kemosparc.

The machines are on the same IP network? And all 4 VMs are also on that network? Do they have static addresses or do they get them via DHCP? Any firewalls running on the Linux hosts?

[kemosparc]

Same physical network/switch.

The 4 machine has static IPs 11.0.0.31-4

Reachable by ping from anywhere on the same network.

Thanks,

On Qemu it works with no problems.
