Web Filter + External blacklist + Whitelist

[technicalcsti]

Hi,

I've setup an opnsense server with the latest stable version as a web filter.

It's configured as a transparent proxy for http and https.

All is working fine except that if i choose to blacklist the "socialnetwork" category using an external blacklist, and I add facebook.com to the whitelist, all social networks, even facebook.com, are denied.

I though that whitelist has priority over blacklist, even external blacklist.

Is it a bug or I did a mistake ?

Thanks,

Kind Regards,

Yannick
