Hi all I have a friend who has asked me to help him setup a small ISP. I was thinking of using ISPConfig as a control panel (instead of CPanel) and billing system. He wants also to run hotspots for some of his clients like in small hotels and lodges. For the hotspot I need a radius server. Can ISPConfig work as a radius server? If so does it require a special module that you buy separate like the billing module? Please, help.
