Hyper-V, VLAN Support And A Virtualized Router

Hi

I have the following problem with Hyper-V and my new VLAN enabled network.
But first, I would describe my environment:

- I have 3 physical NICs in my physical server. 1 NIC is for the host
system, 1 NIC for some virtualized servers and 1 NIC for a virtualized router
(Vyatta VC4 Community Edition).
- I have 2 external NICs configured in Hyper-V network manager. 1 external
NIC is for the servers, the other external NIC only for the Vyatta router.
- I have a HP ProCurve Switch. I have set up a VLAN for all virtualized
servers and configured the appropriate ports (tagging, PVID, etc.) where the
NICs gets connected.

Yes, that's correct. All virtualized servers and the virtualized router are
running on the same physical maschine. But I use different NICs for them.

Now straight forward to my problem: I can not ping the configured VLAN IPv4
address of the virtualized router from any virtualized server. It seems that
the 802.1Q tag will be removed before the package arrives at the router.
When I run the Vyatta router on a VMware server (on a different physical
server), everything works fine (every Hyper-V virtualized server can ping the
VLAN ip address of the VMware virtualized router). Thefore, the HP ProCurve
Switch can not be the cause.

As I have written: I think the 802.1Q tag will be removed from the
virtualized external NIC which I use for the router. Also, I have tried
(without success) the steps which are disclosed in the following post:

What can be the problem? I don't wanna switch back to VMware. But I have to
get the router up and running.

Thanks and Regards,
Dominik
