the VLAN tagged packets can't reach outside network. Is there any needed workaround the bridge?
I tested though with 2 guests on the same host with same VLAN ID, they both can reach each-other. But, 2 guests, on different windows host with the same VLAN ID, doesn't work either. No problem on my switch, as I have multiple mikrotik routers running on the switch and doing VLANs.

Thanks for any advice

EDIT:
* Host is Windows 7 x64 with integrated ethernet adapter: Broadcom NetLink (TM) Gigabit Ethernet
* Guest is Ubuntu 12.04, tested all ethernet adapters type, give the same result.

Here's the network diagram:

Code: Select all

1. 192.168.0.254/24 VLAN ID 0 ====> SWITCH ====> VB Win7 Host 192.168.0.1/24 eth0 bridge==> VB Ubuntu Guest 192.168.0.2/24 eth0
2. 192.168.20.254/24 VLAN ID 10 ==> SWITCH ====> VB Win7 Host eth0 bridge================> VB Ubuntu Guest 192.168.20.2/24 eth0.10

* 192.168.0.254/24 & 192.168.20.254/24 is a physical mikrotik router

The only network that is connected is number 1.

If I set it to:

Code: Select all

192.168.0.254/24 VLAN ID 0 ====> SWITCH ====X
192.168.20.254/24 VLAN ID 10 ==> SWITCH ====> VB Win7 Host eth0.10(set on driver) bridge====> VB Ubuntu Guest 192.168.20.2 eth0

it works except that I can't use VLAN ID 0 on my host

and this also means, I can only use 1 VLAN at a time(for all VMs)

EDIT:
After doing an experiment with WireShark on the host network, I've found out that the host and the guest, are able to accept VLAN tagged packets, but it couldn't get out. I'm concluding, that the bridge are able to accept VLAN tagged packets, but probably somehow it stripped all outgoing packets.

Any advice please? or maybe some wiki I can read from.... anyone

Amazing. No one help

I'm forced to use Mikrotik's EOIP
