I have been using Lync 2010 internally here now for 6 months and the business and I wanted to take it to the next level and enable the external features of Lync.
From what I have been able to gather so far this is pretty much impossible without the use of TMG or ISA. Is this right?
What I have to use at this point in time is;
1x Windows server 2008 R2 Standard x64
1x Watchguard x750e Firebox
With this would this be possible to setup the appropriate rules to publish Lync 2010?
