Hi,
I work for a secondary school in the UK, and we are looking for an alternative internet filtering solution. Currently we are using one provided by the local authority. We have very little control over what ports and sites we can have blocked/unblocked. I have done some reading into free or open source internet filters, but would like recommendations for free/open source internet filter software. Ideally we would like it to run on windows server 2008/2012 just to fit into our infrastructure, but we will go linux if we really have to. The amount of NIC's is irrelevant,
Thanks!
