First up, do you really mean VLAN? VLAN has a specific meaning and I
don't think that you have any. I think you are talking about virtual
machines on a virtual network.
The simplest way to do what you want is to use a virtual machine (not
the DC) as a router between the two subnets. You would give it a second NIC
and put that NIC in the network linked to the host's physical NIC. It will
be in the same IP subnet as the physical LAN machines.
I would set it up as a NAT router. (I have a setup running this way).
This allows the virtual machines access to the physical LAN and to the
Internet without changing the routing on the physical LAN. If you really
need the machines on the physical LAN to be able to initiate a connection to
a machine in the virtual network, the routing is a bit more complex. Your
gateway router needs extra info so that it knows about the new subnet and
how to get traffic to it.
Here is how it looks with a NAT router.
Internet
|
gateway
10.0.0.1
|
physical LAN
10.0.0.x dg 10.0.0.1
|
10.0.0.254 dg 10.0.0.1
RRAS NAT router (vm)
10.1.1.1 dg blank
|
virtual LAN
10.1.1.x dg 10.1.1.1
For full routing between subnets and Internet access, it looks like
this.
Internet
|
gateway (static route 10.1.1.0 255.255.255.0 10.0.0.254)
|
10.0.0.x dg 10.0.0.1
|
10.0.0.254 dg 10.0.0.1
RRAS LAN router (vm)
10.1.1.1 dg blank
|
10.1.1.x dg 10.1.1.1
