[K12OSN] setup transparent proxy for thinclients webtraffic

[johan.vermeulen7 at telenet.be]

Dear All, 

I'm setting up a K12Linux server, that also acts as a router/Firewall for some laptops and workstations. 
So I 've set up a transparent proxy, Squid, for all traffic passing through the box, in order to monitor and control the network traffic. 

But I can't find out how to also reroute al the traffic from the thinclients to Squid as well. 

Does anybody know how to do that? 

Thanks for any advice. 

Greetings, J.
