allow a site

Hello,

you can simply block the fortiguard categories you want (e.g. social networking) and then add in the URL filter (in the same Webfilitering profile) e.g *.twitter.com, as a wildcard with action allow.

Alternatively you can create a custom URL category add the  sites you want to allow in this category and then make sure you allow this custom category in your web filter profile.

thanks,
