Reverse Proxy Planning for Exchange 2013 RRS feed

  • Question

  • Hi,

    We are planning Exchange 2010 to Exchange 2013 datacentre migration for 18000 users and all the Exchange planning is done. Now we are looking at planning of Reverse Proxy solution. We will be publishing different URLs for OWA, ActiveSync and Outlook Anywhere. UAG has been finalized by the organization. I don't find any document or links which suggests the planning of Reverse proxy for Exchange. Can you please let us know the sizing of UAG with respect to Exchange 2013. Thanks.

  • Hi 

    Sizing as far i know there is no sizing document for UAG 

    But Minimum you need to have UAG 2010 SP3 to work with Exchange 2013

    You can see the support boundaries for UAG below technet

    http://technet.microsoft.com/en-us/library/ee522953.aspx

    Note : UAG requires each user to have a CAL

    You can also try 2012 R2 web application proxy . This does reverse proxy without the need of CAL's.

    You can give it a try if you wish to go with web app proxy and you can see below

  • Thanks Sathish, Is IPSEC is supported with IIS ARR because we need to secure Outlook Anywhere using IPSEC. What are the drawbacks and benefits of using IIS ARR ?

    Yes with IP sec It is possible through IIS ARR. here is the similar link for you

    Advantages 
     If you want is a less expensive way to provide high availability/scalability for a relatively smaller and medium environments its the best.
     You have the sticky sessions which is client affinity as an option which can be configured

    Disadvantages 
    Managing large IIS ARR server configurations or multiple servers over the Internet can be difficult.
