Thanks for the reply. Note that Using MAC addresses I did have a problem with my son’s desktop computer (not laptop) in that he used a wifi dongle (renting and can’t route an ethernet to him). Due to the way the usb dongles work, his MAC address changed when he unplugged and plugged the dongle back in. It would be nice if the router could be designed so that they were identified in some other way, if not by Static IP.
About whitelist/blacklist, you are saying that in an HTTPS, you cannot whitelist a subdomain (eg. myblog.blogger.com) if the domain is blacklisted (eg. blogger.com)?
