So, if I were to enter some bogus ip/secret/etc in the radious 
settings (to enable radius server auth, even if i don't have such a 
server), and omit the fields on the portal page (so no actual auth 
requests will be sent to my non-existent server), I'd effectivly have 
MAC filtering with a nice "Error" page shown to those not listed in 
among the allowed MACs?

I find this a very nice "feature" (side effect?) Since it will allow 
me to do MAC filtering AND displaying a legalese "scare crow" page to 
anyone not on the list trying to get through ;)

Is it still necessary for any clients with "From IPs" to start their 
WAN sessions with a http request to get through?

If so, any chance this will change in the near future?
