Block outbound traffic to certain IPs with Windows 2008 R2

Specs: Windows 2008 R2

I have a Windows 2008 R2, I am using the built-in Windows Firewall with Advanced Security to block some outbound traffic to specific IP addresses/protocols. While this works perfectly on the server itself, it doesn't affect the workstations which are using this same server as their gateway to the Internet (We used Routing and Remote Access (RRAS) to provide NATing to the clients).

So how can we make these policies affect the traffic passing through the RAAS?

You would need ISA server or similar product to do so.

Answers are only as good as the information you provide.

Indeed, I am aware of this, but, ISA won't run on Windows 2008 R2, and Forefront TMG 2010 won't run on Windows 2008 R2 if the same machine is a domain controller, which is my case.
So what do you suggest as an alternative?

If your trying to block traffic to specific ip addresses to the internet, perhaps using your firewall to do the blocking could be a good alternative. If the ip address you are trying to block access to are internal and you have a smart enough switch, you can block at that level - just another suggestion that might be feasible.
