TMG in NAT mode with WPAD alternatives for Windows Server 2012R2 ?

Hi there,

We have been using TMG on WinServ 2008R2 to provide internet access to students for quite a long time (have started with ISA).

Now Microsoft market is based on Windows Server 2012R2 OS. I do personally like some of the new features of new OS,BUT TMG can not be installed on WinServ 2012R2 !!! 

So, are there any alternatives for TMG NAT on 2012R2 ?

Regards,

Alexey K.
