I’m facing an issue that i did not found an answer after hours of search.
I’m using Ipfire in a school, standard usage, 95% windows clients:
- Green for LAN clients and network printers.
- Blue for Wireless clients
I actually using the proxy in transparent and non-transparent mode (via WPAD) + forcesearch activated and everything works fine.
Anyway, wireless (blue) clients can disable proxy in their browser or in windows parameters. This is my problem.
I tried to tick the option “drop all packet that are not addressed to proxy” but:
- it broke WPAD
- it broke firewall rules that allowed Blue clients to access network printers on Green, they cannot access printers any more.
So my question is, how to deny internet access from clients that do not use proxy from Blue without to avoid them to reach network printers on Green network?
My English is a bit limited, sorry for that, and thanks in advance for answers.
