I have a RB422 running v 5.22 and I have the rb setup for hotspot access with authentication to a remote RADIUS server. All is working well. The owner gives out the password to the guests who come into his shop. Unfortunately some guests live above this coffee shop and have started downloading illegal content. I don't know if there is a way to block certain type of sites, not by URL or is there a way to better track the URL's visited. The problem is that everyone at this location is using the same username and password and there is no way to differentiate between the users. I also have NAT enabled so they are not getting separate public IP addresses. Thanks for the help.
