Yes I know it's a big ask & I know there is URL Filter but it does not seem to allow filtering according to user & their group membership.
For example:
User1 member of group1 has no access to the internet.
User2 member of group2 can only surf the whitelist
User3 member of group3 can view anything as long as it's not on blacklist
User4 member of group4 has unrestricted access to the net.
Yes I have children boys & girls so hence the question.
Any other suggestions or alternative addons will be seriously considered.

Thanks.
