F5 with Lync 2010

Hi,

 

Currently at a client site, helping them load balance the Lync Servers using F5 and running into some configuration issues. My setup (Image attached) is all configured but I am confused about how to configure the internal Interface of Edge Servers on F5. I mean do I use SNAT for traffic leaving the Edge Servers to the Internal Network towards Front End Servers or configure F5 to act as DG and then the F5 should forward the traffic to the Firewall. Please look at the image and suggest me on how F5 should be configured.

    Hi Amit, the topology we've tested would have the Edge internal virtual servers located on the F5-2 BIG-IP, not F5-1. You would SNAT the traffic destined for the FE servers at F5-2.

     

    The Lync iApp is based on this topology. Are you using the iApp template?

     

    thanks Mike
