Nicely done, currently i just used my pfsense to control the users using the captive portal local user manager :-) . Version 1.2.3 RC1 now available! can control user download and upload speed for the users. I feel so kejam using bandwith metered package for WiFi users,i just prefered to set the days example 1 day 7 days or 30 days for their access . Using the 1.2.3 RC1 you can set max download and upload for the users. So it will be equal to all users that connected to the network.

Anyway your interface are great can be sell to enterprise users who wish to sell hotspot system :-) .
