SBS 2011 as a Hyper-V Guest

    Question

  • This is another of those questions I'm almost to embarrassed to ask........

    Small office with a single external IP address.  There is a brand new server and the plan is to use it a a Hyper-V host.  On this host SBS2011 will be installed as a guest.

    How should the DHCP be handled?  I'm assuming that the Windows Server 2008 can't do it as there will be a virtual SBS 2011 doing the job. 

    Would I be right in thinking that the 2008 box should just be a standalone with a static IP talking directly to the ISP?  If so, I'm guessing that the office in question will need two external IP addresses - one for the 2008 box and one for SBS 2011.

    Alternatively, should the router handle the DHCP - handing out IP's to both the 2008 box and SBS 2011?

    Thanks in advance for any input.

  • Hello RW, and a good question.

     

    Here is a suggestion that works 99% of the time.

     

    Give the Win Server 2008 (or box 1) a static Private IP.

    Give the SBS 2011 (Virtual Machine box 2) a static Private IP.

    Let your (Router) have the public external IP address assigned to it. Then you can just map the traffic\ports to SBS 2011 for the remote access or exchange if you have standard.

    SBS 2011 (Virtual Machine box 2) should handle dhcp for regular workstations on your network.  Long as you have the correct settings for DNS and the default gateway, things will work fine.  See example:

     

    Box 1: 192.168.0.2 (Static LAN)

    Box 2: 192.168.0.3  (Static LAN)  Provides DHCP services assigning 192.168.0.1 as Gateway.  Provides 192.168.0.3 as DNS

    Router: 192.168.0.1 (Static LAN)  &  205.XXX.XXX.XXX (Public WAN)  Make sure your router has the correct Public DNS setting.

    Hope this helps.

  • Hi,

    No your router should be connected directly to the internet. Configure the Windows 2008 (R2 I hope) hyper-v host with a static ip address in your internal network. Install SBS as Hyper-V guest with a static ip address in your internal network, both have the internal ip address from your router as gateway configured.

    Let the SBS server just handle the DHCP.

    This all can be done fine with just one public ip address.
