I am hoping someone will be able to tell me how I can block facebook from our sonicwall. I have tried implementing key words, using a drop page rule (which worked for a while), blocking social networking with content filtering but now regardless of my efforts I can't seem to block it. It even blocked it when I tried to submit this question because facebook is in the keywords but it wont block the facebook webpage. The Sonicwall "engineers" from whatever outsourced call center have been no help whatsoever.
We are a small public school and our policy does not allow for the use of facebook. I am not looking for a lecture on why we should leave it open, as has happened before, this is our policy and I would like to figure out a way to get our sonicwall to restrict it. We have a sonicwall TZ210 with enhanced sonic OS and content filtering. Thank you for any suggestions you may have.
I would also like information on how to get the sonicwall (if possible) to filter google images as safesearch isnt filtering anything as soon as a user logs into their google acount. Thanks for the input.
