NAT with caching and filtering

I have 2 routers both running Windows 2000 server.
The first router is connected to the Internet and the second interface is my local network. This first machine is running NAT and seems to work fine. The second router is running both DHCP and DNS for my internal network and properly routes all external traffic throught NAT and server 1 and works fine. I have setup AD on the second router also. (Server 1 logons to this domain)

I have been asked to do 3 things which I am having problems finding solutions/answers for.

1) Use HTTP and FTP caching. This must be done without adding any other software other than stock Windows 2000 features. I have searched through NAT and don't see any place to do this.

2) Traffic filtering. I know how to block traffic to specific ports, but I need to block traffic to specific web sites. Again 2000 features only.

3) Make sure VPN can use L2TP and IPSec through NAT.

Any suggestions or pointers greatly appreciated.

No good news here. Without a third party software or hardware solution that provides additional filtering over and above port filtering and NAT, there is no way to do any of the things you describe on a network-wide basis. Each individual can control the caching settings and block content on their own desktops through IE settings, but there is no way to control this network-wide that is built into Win2K.

Hope this helps!
