Hello, we are implementing a squid proxy server in my office. The principal idea is to limit bandwith using delay pools and also block some websites. We have made our config and its working, but we dont know if everyting is correct specially in the delay pools part. **Introduction: We have dedicated broadband with : 4MB FOR INTERNATIONAL TRAFIC 100MB FOR NATIONAL PROXY: 192.168.169.3 GATEWAY: 192.168.169.2 Users: like 150 daily **We want to divide our internal lan in 5 groups with the following rules PER USER. GROUP 1: normales from 192.168.169.30 to 192.168.169.129 -If a user exceeds 10mb when downloading a file limit to 10kb of download speed. GROUP 2: tecnicos from 192.168.169.130 to 192.168.169.149 -File bigger than 50mb, limit to 30kb GROUP 3: administrador 192.168.169.150 to 192.168.169.189 -File bigger than 100mb limit to 30kb GROUP 4: estudio 192.168.169.190 to 192.168.169.219 -No downloads for files or very slow, but freely web surfing including youtube. GROUP 5: gerencia 192.168.169.220 to 192.168.169.252 -Everyting unlimited **We want to block the following sites from 192.168.169.1 to 192.168.169.129 : BLOCK: [CODE].facebook.com .twitter.com .doubleclick.com .fotolog.com .warez-bb.org .fotolog.cl .chilewarez.org .rapidshare.com .megaupload.com .rapidshare.de .mediafire.com .hotfile.com .myspace.com .fotolog.terra.cl .fotologs.com .portalnet.cl .taringa.net .antro.cl .chilewarez.cl .chilebt.com .shared.cl .comparte.cl .mininova.org .torrentz.com .flickr.com .flicker.net .keepvid.com .kotteshiro.com .no-ip.org .no-ip.com .redtube.com .xnxx.com .muyzorras.com .bananacorp.cl .orgasmatrix.com .depositfiles.com[/CODE] **From: 192.168.169.130 to 192.168.169.149 BLOCK: Same as above unless facebook.com **Deny from 192.168.169.1 to 192.168.169.29 DOWNLOADING THE FOLLOWING EXTENSIONS: [CODE].exe .mp3 .vqf .tar.gz .gz .rpm .zip .rar .avi .mpeg .mpe .mpg .qt .ram .rm .iso .raw .wav .mov[/CODE] [B]We dont know if the rules per group are possible with the bandwidth we have, also everyone surfs a lot youtube, we need that to not eat so much bandwith[/B].
