VB networking on MACOSX

[brownbytes]

Hello All,

I am currently running ubuntu VM on MAC OSX. I am trying to bridge multiple interfaces , but facing connectivity issues

set up:

Default router : 192.168.1.1

Physical machine:
MAC OS : eth0 (physical NIC) 192.168.1.115
MAC OS: eth5(USB<-> Ethernet) 192.168.1.116

VirtualBox:
eth0 -Bridged to MACOS-eth0
eth1-Bridged to MACOS-eth5
eth2-Host Only Adapter

VM:
eth0 192.168.1.117
eth1 removed IP (No IP)
eth2 192.168.56.102

Now, I am running another virtualised environment (VE) within the VM which comprises of a switch(sw1) and a host(h1).
I have binded switch(sw1)'s port to VM's eth1 (with help of internal function provided by VE), so I am imaging host(h1) is logically connected to the default router via the switch(sw1).

When I try to ping the Default router from the host(h1), though I see exchange of icmp requests and reply on physical machine, I fail to receive them in the host(h1).
Please note I have manually configured the arp table in host (h1) .

The same setup works perfect if eth1 is a NAT adapter and not a bridge adapter.

I understand without VE details replicating the issue is difficult, but any pointers as to where I can start looking would be very helpful. Also let me know if any further details are needed.
Thank You

Do you see them in sw1?

[brownbytes]

nope.

I dont see the packets on switch interfaces.

Configure the promiscious mode of the VM to "Allow all". Then you'll need to configure your other virtualised environment to do the same basically.

[brownbytes]

awesome!

thank you for that. I did try promiscuous mode earlier but allowed only vms. Allow all resolved the issue.

Thank you very much
