FreeRadius to authenticate DHCP Requests with Option82

[Marinko Tarlać]

Hi

Can you tell me something about performances?

I'm using Mtik as NAS for PPPoE users and 500-600 online users per 
server is optimum according to my experiences (Quad core server, 2GB 
RAM,...).

ISC DHCP works very well for >6000 users and the same number of cable 
modems but I'm not sure is Mtik capable for something like that...

ISC problem is database integration which won't be added in the next 150 
years... :)
