I was hoping someone could explain to me the differences between RRAS, ISA Server and Forefront Threat Management Gateway. As far as I can tell they all sort of do exactly the same thing?
RRAS allows Routing and VPN on Windows Server 2008.
ISA Server 2006 (although not compatible with Windows Server 2008) and Forefront TMG 2010 provides Routing, VPN and Firewall...
But seeing as Windows Server 2008 comes with its own Firewall, why would anyone need to use ISA or TMG? Is it just for convenience/easier management?
I was pretty annoyed to discover that ISA Server isn't compatible with Windows Server 2008 (and that TMG isn't included in any MS subscriptions), but then I discovered RRAS and it made them both seem rather pointless.
Is it true? Thanks for any help in understanding this.
