Edge Server Configuration with one NIC RRS feed

  • Question

  • hi all,

     

    I have researched through several web sites as well as blogs to find out the rigth anser for our scenario.

     

    In the enviroment the DMZ design will be changed and this will impact the current Edge Server deployment. In the current configuration we have two NICs and for the new design we have to change the design for one NIC configuration.

     

    The Edge Server was deployed in consolidated version and has 4 IP addresses.

     

    Do your guys know it is possible as well as supported scenario to deploy the Edge Server in consoldated version with one NIC?

     

    In the OCS_2007_Support.doc I found out that the Access Access and A/V Conferencing Role are clear supported but the Web Conferencing is not clear?

     

    Is there someone who was tested this kind of scenario as well as the experiences?

    Access Edge Server

    An Access Edge Server is required for external user access unless that access is through Communicator Web Access. Only a single Access Edge Server or a single load-balanced array of Access Edge Servers is supported for federation and public IM connectivity. Only a single Access Edge Server or a single load-balanced array of Access Edge Servers is supported for remote user and anonymous user access. You can have a different Access Edge Server or array of Access Edge Servers for federation and public IM connectivity than the one used for remote user and anonymous access.

    Two network adapters, one for the internal interface of the Access Edge Server and one for the external interface, are supported and recommended. A single multihomed network adapter for both the internal and external edge is also supported.

    Using different DNS names for each of the two interfaces is required. A unique IP address and a unique domain name are required for the internal and external interface. A multi-homed network adapter that uses the same DNS name, and therefore the same IP address, for both internal and external interfaces is not supported.

    An Access Edge Server is supported by both the Standard Edition license or product key and the Enterprise Edition license or product key.

    Joining the Access Edge Server to a domain is supported but not recommended.

    Web Conferencing Edge Server

    A Web Conferencing Edge Server is required for external users to participate in conferences that are hosted by Office Communications Server 2007, Web Conferencing Server.

    A/V Edge Server

    An A/V Edge Server is required for sharing audio and video with external users.

    The external interface of the A/V Edge Server must have a publicly routable IP address. If an external firewall is deployed, it must not use NAT (network address translation) for this IP address. This requirement does not apply to other edge server roles.

    The IP address of the internal interface of the A/V Edge Server must not have NAT applied to it. If an internal firewall is deployed, it must not use NAT for this IP address.

    Two network adapters, one for the internal interface of the A/V Edge Server and one for the external interface, are supported and recommended. A single multihomed network adapter for both the internal and external edge is also supported.

    To my knowledge any Edge server is NOT supported with only a single NIC.  I have tried it and it didn't work, as have others.  I have read/heard about a few people getting it to work.

     

    That said, there is a slighty 'vague' statement in the documentation that leaves the definition of "multihomed" up for interpretation:

     

    "Two network adapters, one for the internal interface of the Access Edge Server and one for the external interface, are supported and recommended. A single multihomed network adapter for both the internal and external edge is also supported."

     

    I'm going to see if I can get a clear answser from MS on the exact 'supportability' to clear this up once and for all, as I've received conflicting information from different sources.

  • As promised, I researched this a bit further and got some input from Microsoft and the MVP team:
