We are in the process of deploying UAG for a client. We will be using 4 UAG Servers in a array and planning to use F5 as a Load Balancer. My question being : Do we need F5 LTM Solution for Internal interfaces of UAG too or can we just use one F5 Device for the Public side interface of UAG. My confusion comes from the information that the sessions are initiated from outside->In and hence, we only need to load balance External Interface. Had it been TMG, I could have understood but what would the reasoning behind UAG.
We will be publishing LYNC, SharePoint Server, TFS etc. using UAG.
