NIC settings with Weak/Strong Models RRS feed

  • Question

  • Quick question I'm guessing that the UAG 2010 needs to be configured similar to Edge Exchange/OCS servers? I know that on 2008 is different than 2003 because of the weak/strong nic models. I had a ____ of a time with Exchange 2007 on Server 2008 SP2 because of the IPv6 issues. Ended up going back to Server 2003 to solve the problem for now.

    UAG is only going to be for Publishing OWA 2010

    My question is this
    External
    218.212.192.109
    255.255.255.0
    218.212.192.254

    Internal
    192.168.1.226
    255.255.255.224
    192.168.1.225

    With Server 2008 should I gave both NICs default gateways? Or should I just give the External a default gateway and then create a route -p add entry for the 192.x.x.x network?

    Just want to make sure I have this configured right and I'm not fighting with routing issues like I did with Server 2008 and Exchange 2007 with the IPv6 stuff.

    Should I disabled IPv6 ? if I'm not using it as well?

  • Only DNS on internal interface!
    This is where the machine must have primary DNS to find AD and other internal stuff.

  • Internal!

    To summarize you should have the following on each NIC (in Binding order ;-) )

    Internal NIC
    ------------
    IP : Yes
      Advanced settings
      Register in DNS : Yes
      Enable NetBIOS : No

    Subnet mask : Yes
    Default Gateway : No
    DNS : Yes
    Client for Microsoft Networks : Yes
    File and Printer Sharing for Microsoft Networks : Maybe, if not sure then Yes

    External NIC
    ------------
    IP : Yes
      Advanced settings
      Register in DNS : No
      Enable NetBIOS : No

    Subnet mask : Yes
    Default Gateway : Yes
    DNS : No
    Client for Microsoft Networks : No
    File and Printer Sharing for Microsoft Networks : No

  • Only gateway on external nic.
    Add routes if more than 192.168.1.224/27 is required for internal.

    Keep IPv6 enabled on UAG, even if you do not use it.

  • Hi Kent,

    Just to add to OPs Question, How about DNS settings?

    Do you keep them on Internal or External or both?

    (Just to clarify)

    Great thanks it so hard to clear this up... I wish someone at Microsoft would do a nice blog on different NIC configurations with real world examples. I think with 2003/2008 having different models. Plus all the new Edge products such as UAG, Exchange, OCS, etc this is something that would be a great white paper to have.

    If you get a second please post on AdrianOconnor

    Should both Internal and External use the same DNS server? Right now I have Internal using my internal DNS and External using an external DNS.

    One other question, what about NIC binding order? Should the External be first or the Internal? Right now I have the internal first, because if external is first.

  • Ok last question, binding order?
