Web filtering in small primary schools?

[fxlite]

I've used pfsense with dansguardian a couple of times...it's not that hard to set up and works fine with ldap.

 

You have to use legacy adapters in Hyper-V for pfsense, though...and you have to up/down the interfaces for them to work properly sometimes.

 

Just any old machine with 2 nics you've got lying around would do.
