WPAD/SquidGuard - How to force client using it?

[Big80]

Hello,

I followed the documentation: https://docs.netgate.com/pfsense/en/latest/cache-proxy/wpad-autoconfigure-for-squid.html

Everything's works fine but the client can bypass the proxy (just by disabled the automatic configuration in the browser). How to force the client to use the proxy/SquidGuard?

Also, I don't understand the part "Block Port 80 Out from LAN"?

Thanks.

The way you force it is to block port 80/443 on LAN, just like it says. Put a block rule on your LAN firewall rules to prevent access to tcp 80 or 443. That way, nobody has web access unless they go through the proxy server. Put an allow rule for the alias Exempt_From_Proxy or something like that for clients that you want to allow out directly.
