i have a windows 2000 server connected to internet through VSAT. i can connect with the ISP proxy port no. 9887 and i can share my internet connection through my local network through port 9877. My problem is i cant control the work station through accessing porn sites. So my question is, is it possible to have two proxy server 1st is the windows 2000 advance server that is directly connected to ISP and the second is the slackware with apache proxy. and all my local network is connected to the second proxy but still it can connect to internet.. if possible pls give me some tutorials.. tnx!

I think you should be able to daisy chain them. The easier solution would be to make the apache proxy a dual homed gateway, where the eth going to the isp sees the win as a proxy? (btw, squid + squidguard?)
