Hyper-V: Problems accessing host

Hi community,

I already tried to get help in the german group but without success, so I'll
try here too...

Host 2008 64bit
actual Intel VM capable chipset, latest drivers, updates etc
2 NICs
Firewall task running but disabled
Domain Member

VM 2008 32bit
DC (there is another "real" DC)
FW running, but disabled

external network, host and vm in same network on the same NIC (there is
another VN using the other NIC for 2 other VMs in a different network)

host and vm have access to the internet and all other machines in the LAN
all machines in the LAN have access to the vm
pinging the host is possible from vm and LAN
access to the host from LAN possible (RDP, NETBIOS etc)
access to the host from vm not possible (but ping)

What might be the problem?

Frank

1.) Disabling the firewall is the wrong answer. Enable it, but give it an
access rule that supports the kind of access you want.
2.) Sharing a NIC with the host and VM can be a problem. There's a good
reason that the recommendation is to have a separate NIC for host
management.

Of the two, I strongly suspect #1. But also look at updated NIC drivers for
the physical NIC on the host.

Hi Charlie!

Thanks for your reply.

Why? I don't need any firewall. There are 4 VMs running on the host. So I
have to run 5 firewalls and use resources for 5 firewalls and depending
services and use my time and nerves to describe access rules even if
everybody and every machine is allowed to use any port and any service on any
machine? That makes sense...

All drivers are the latest available...

I just added another NIC but setting it up it I'm not sure about the correct
configuration:
The physical NIC used by the virtual network is, however, also seen in the
network configuration of the host (extern VN), so of course it has an IP for
the host. Shall I remove the GW and use another IP of the same network and
add the GW for the new installed NIC?
Or is there some hidden feature to give the VMs access to the physical
network without having the host use the same NIC?
