Replace TMG Forefront 2010, what shall you do?

As we all know the Forefont TMG 2010 is a Product that is about to end. Microsoft has said this: Microsoft announced the Forefront TMG 2010 product will be discontinued. Microsoft will continue to provide mainstream support for TMG until April 14, 2015.

Based on this we have to do something about it. From what I see there are several ways to fix this:

1. F5/BigIP as reverse Proxy, well it's not cheep but can fix this.
2. ISS WAP, well you need to setup ADFS and this takes some time, and time is Money :-)
3. ISS ARR, it's good for Lync 2013 and Exchange but be aware of server OS Version, ISS ARR Version, or you will not get it to work. I used Windows 2012 (NOT R2) and ISS ARR 3.0, and it worked for Lync 2013.
4. KEMP, it's not for free but it easy to install, easy to work and you can it running as VLM. The smallest one cost about 1600 EUR inkl 1| year basic support.

The install of KEMP is easy and they got great templates. I have tested the ISS ARR, F5 and KEMP and from my view the KEMP is one of the best and you get all functions included in one lisence. If you then use the HLB functionality it's in the same lisence.

So from my view I think it's time for you who has Forefront TMG 2010 to start to plan for the future.
