>> Hello All!
>>
>> I have a Virtual Host running W2k8 RTM with Hyper-V
>> the machine has three physical adapters:
>>
>> 1. Connected to Internet router - available for VMs
>> 2. Connected to LAN - available for Virtual machines
>> 3. Hyper-V server management adapter.
>>
>> I set up a Windows Server with RRAS on one VM. I can access both Internet
>> and LAN from it, routing is ok. If I use it from workstation located on
>> LAN they can go yo Internet too, no prob. The issue starts when I try to
>> use any VM. Ping Internet router through RRAS from any VM gives me the
>> first reply - all other requests temes out.
>> On networking trace I see the first packet is ok, other three ping
>> requsts have an incorrect header checksum.
>>
>> I built another router on a fresh VM (this time with ISA 2006) - the same
>> story - I can access Internet from my LAN but only in case I use a
>> workstatio other then a guest machine on the same Virtual Host as RRAS.
>>
>> I used this configuration for Virtual Server and Virtual Iron before and
>> everything worked fine, but Hyper-V does not want.
>>
>> I am wondering if anybody tried to build ISA or router under Hyper-V and
>> if it is working?
>>
>> Thanks,
