Making a W2K with Internet Connection Sharing secure

[Sarbjit Singh Gill <ssgill () starhub net sg>]

Greetings,

I am a part of a group of volunnteers who help with 
teaching underprivileged kids in orphanages.

we had some donation of softwares from Microsoft and 
hardware from HP and DSL connectivity from a local 
telco.

The setup looks something like this :
DSL modem connected to a multi homed Windows 2000 
Server. The W2K box is then sharing the ADSL 
connection via Internet Connection Sharing to the LAN 
made up of 10-25 PC running W98,WME and W2K Pro.

I need somekind of proxy/NAT/firewalling  and URL 
filtering capabilities on the W2K. They have to be 
free. We are sourcing for some netscreen stuff but do 
not know when it will come in. 

I can't use IP filtering in W2k as it affects all 
adapters. The LAN PCs use the server as a DC for 
policies and authentication. 

Right now the W2K server is connected to the internet 
with no security whatsoever.

Thanks in advance.

Gill
