Rverese proxy sugguestions - any reason not to use ISA2006 anymore?

Question

This is a silly question, but im just looking to publish meeting content outside the organization to external users, is there any reason for me not to use the old reverse proxy i was using for OCS2007 R2 which is ISA2006 ? i know its out of support and
all of that but fundamentally it should do what i want it to do should it not? or are there any gaping security holes in the product i could drive a truck through?

Answer 1

I believe ISA2006 will work for simply publishing Lync Web Services. (there wasn't too much of a change in how the publishing works from ISA 2006 to TMG that I can recall.)
I am not aware of any giant security holes in the product, mainstream support did end in 2012 and I haven't seen any updates beyond 2009.
A couple other alternatives if you don't have an appliance you can use (i.e Kemp/Citrix/F5 Loadbalancer) are:
IIS ARR http://blogs.technet.com/b/nexthop/archive/2013/02/19/using-iis-arr-as-a-reverse-proxy-for-lync-server-2013.aspx
Windows 2012 R2 WAP http://blogs.technet.com/b/dodeitte/archive/2013/10/29/how-to-publish-lync-server-2013-web-services-with-windows-server-2012-r2-web-application-proxy.aspx
In fact: Microsoft actual suggest that you can use ISA here: http://technet.microsoft.com/en-us/library/gg398069.aspx "You
can use Microsoft Forefront Threat Management Gateway 2010, Microsoft Internet Security and Acceleration (ISA) Server 2006 SP1, or Internet Information Server 7.0, 7.5 or 8.0 with Application Request Routing (IIS ARR) as a reverse proxy."
