    Squid / DansGuardian on dedicated redundant pair, tho' with Smoothwall on a system as the outer F/W.

    Honestly, Squid/DG was set up before I started testing Smoothwall. The Smoothwall has been working great, but Squid/DG have worked so well there's been no reason to change the configuration.

    ISA 2006 - Will be upgrading to forefront TMG in the not too distant future

    Worth noting for anyone not running behind such a device that using procurve manager you can scan and connect to other schools switches! at least you can in SWGfL anyway!

    I saw your post about the proxy you use and I am currently using the same config. I.E. SQUID with K9 Web filter. Proxy works fine and users only gain access to sites allowed through K9, however they do not get the K9 splash screen if a page is blocked. They just get page cannot be displayed...

    Is this something you have managed to get working ?

    Is that for all sites? It's kind of expected behaviour with HTTPS, but can't think why it would break under HTTP.

    It is for all sites - K9 redirects the user to it's own splash screen on the localhost port 2372, but I'm assuming as nothing is hosted locally on the user PC, this is why it gets page cannot be displayed. It's no big deal, but would be a nice to have..

    I use Squid on Debian in school, which uses the LEA proxies as a parent. The Filtering is also all done by the LEA.
    According to Calamaris squid monitoring tool.

    Average speed increase: 46.98%
    Bandwidth savings in Percent: 34.45%

    I guess thats good ?

    Relatively. I "rule of thumb" 25% cacheability in a school environment.

    We use Censornet, and our LEA uses Bloxx.

    We have been using Smoothwall SG for the past 3 years, before that censornet and before that Squid. Although we are carrying out a review of internet service provided here so this thread is interesting seeing how many are using Forefront TMG and SW but very few others.

    We run a nested proxy here. Our internet connection is provided by our local council, who run a proxy with caching. We connect into that via A 10mb Telewest Fibre. We run a Forefront TMG server which acts as a local proxy which does all of our site side web caching. That way, sites can be served across LAN if already in the cache. TMG web chains onto the external proxy that handles the majority of the web filtering. Eventually, I'll get round to adding some filter policies of our own via TMG

    I like to think Forefront's popular because its cheap, and many people already have ISA, and we're popular because we're GOOD
