Web Proxy Filtering and Caching / Authorized users are bypassing blacklist?
« on: August 29, 2022, 03:42:45 pm »
I have squid setup in a simple forward proxy configuration. I have a short whitelist, a blacklist of *, and that's it. Everything works as expected without authentication enabled. When I turn on authentication though, the authenticated users ignore the blacklist and can access any domain. The unauthenticated users can only access the whitelist still. My goal was to have authentication required all the time but still enforce the white & black lists. Is this not possible?
I don't know enough about squid.conf to say, but it looks right to me if it short-circuit evaluates, since these commands appear in this order:
I guess because we hit the allow whitelist before the allow local_auth, it doesn't care if they're authorized? Any easy way to make it deny everyone who isn't in local_auth? I assume no matter what the GUI isn't going to do what I want and I have to manually modify squid.conf from now on.
