[NTSysADM] TMG Proxy Replacement

[Tanya Pinetti]

We brought up a new data center and need to configure a local proxy server so 
servers can access the internet.  We do not allow servers to have direct access 
to the internet.  Our other data center has TMG, but we don't have enough 
licenses and would like to explore a replacement for TMG.  I only need it for 
proxy purposes so something simply would be ideal.  Any suggestions?  I'm 
looking at UAG, but maybe there's something better our simpler out there.  
Thanks.
