Hyper-V virtual network question

Scenario:

1 Hyper-V host running 08 R2, it's primary nic is on a 10.2.1 subnet.  It will house VM's that need to be addressed on a 10.2.3 subnet.  But since the host is 10.2.1 what is the best way to setup the virtual network so clients can access to vm's on 10.2.3 and I can still access the host on 10.2.1?

you can create a network switch for your new network, but do you have a router between the different subnets?

There is a layer 3 core switch here that's the GW for all subnets at this site.

Dual on-board nics.  So all involved is creating a virtual network under the virtual network manager.. would it be external, internal or private?

do you set the switch port for your primary nic (the one thats used by the os) as a trunk or as a normal port?
It’s should be a normal access port. The other one, where the second physical NIC is connected too but it must be in different VLAN on the switch. Then you will need to find out how to configure the routing between both VLANs: the default VLAN (where the first server NIC is connected) and the new VLAN. Generally, you need a router to do it but it can be done on a layer 3 switch also depending on the switch OS.
The routing is already in place as these are established vlans.. my confusion was on the proper networking config on the hyper-v boxes themselves..
I would suggest searching Internet for “Hyper-V 2008 R2 networking” – there are many examples, one may be suitable for your situation. The option “Allow management operating system to share this network adapter” appears in Hyper-V 2008 R2 only.
Certainly.. except you get a literal ton of crap that's not related too.  I had thought posting here would be easier and faster.
