Hi all,
I have a d-link router and I deny access to several sites. For some reason or another some students have been gaining acces to websites I have blocked using iproxy. Is there a way I can block iproxy from the my users?
Need some professional help Please!!!!

Sounds like a "school"? How large of a network? Is there a domain controller in there, active directory? Any other content filtering going on? Websense is common in schools. Any blocking of the anon proxy services?

I work in a small high school with 200 students and about 120 pc's. I have one main d-link router. I also have a windows 2000 server along with a dhcp server. I'm quite new to this layout so I may need some professional help. I'm sure the win2000 server has a domain controller and possitive it has an active directory.
any suggestions?

A big network like that...I'd not want a home consumer grade router doing the job. Have you looked at Websense?

What model is the Dlink? Is it a commercial grade unit?

Well , you didnt give enough info about your Dlink router. So im assuming its just acting as a NAT device aka Internet sharing device for your school. If you really want to force your users / restrict them then just get a single linux desktop , use iptables to force all HTTP requests through it while running dhcpd. You can use HTTP Cache SQUID
http://www.squid-cache.org 's content and URL filtering to accomplish this task. That way your users will also get cache hits and end up having nicer browsing experience.
