I have a Sonicwall TZ 170 and am trying to figure out the best way to lock down internet access. Right now I have a rule that allows all http traffic out to the internet - so more or less if the user has the proper gateway specified, they can browse. Is there a way to lock this down a little better? I'd prefer to only let specific IP's to browse or certain users. Bottom line is I need to lock down internet access a little better. Thanks in advance!
