Edge NIC's Question RRS feed

  • Question

  • I am trying to implement an edge server for SFB 2015 in a new deployment. I am following:


    and he says the edge server MUST have 2 NIC's configured? I am trying to understand what he is talking about. Do you have to configure your edge server with 2 NIC's? The edge server is on the perimeter network and has access to AD DS.

    Also edge server is behind a NAT device

  • Hi forgiven,

    That’s correct.

    Edge server is the required component for external access.
    When deploying Edge server, you can’t add it to the domain, it needs to be a workgroup computer. Because it is required for external access, in order to ensure the security, you need to deploy it the DMZ area.
    For the network adapter, you must have two network adapters, one for internal access the other one for external access.

    You can use three public IPs (one to one) NAT to three private IPs for Lync Edge access service, Web Conferencing service, and A/V Edge service. You can also use one public IP for the three Lync Edge services.

    The following document describes how to deploy Edge server for Skype for business, please refer to:

    Hope this reply is helpful to you.

  • Hi Alice,

    We have the similar scenario where currently we only have one subnet available for use within DMZ.

    Could you please explain what is the underlying reason why we need two NICs and why "The internal and external subnets must not be routable to each other"? If we use two NICs and configure two IP addresses within the same subnet for these two NICs, what will happen then?

    Thank you!
