I can't for the life of me figure out how to do this in Tomato. If this feature isn't implemented then I'm not sure why because it seems easy enough to do. I couldn't figure out how to do this in DD-WRT too. Am I that stupid? If it can't be done through Access Restrictions, would it be possible to do the block through the Tomato firewall? I have no experience with these scripts so I'd need some help. Thanks!
