Hi, load-balancing between the radius servers is not necessarily needed. I think the servers we're going to by will be capable to manage all dialin accounts. So the radius servers will be in fail over mode. If the first one is up, all requests will be handled by it. If it fails, the second one wi

Hey Sebastian, I think that you are making a rather not too complicated task very complicated with your view of the clustered solution. First you should decide what you want to load balance, the freeradius servers, the database servers or both? I also don't understand the need for some NASes con

Hey Sebastian, I am unsure what your end goal is but consider the following: The FreeRADIUS serves will be load balanced by something like LVS, where you'd have a single IP address shared by both servers, requests will go through either of them (not both). Or you can go for the fail-over situatio

Hi, we're planing to reinstall our Radius servers. Currently we have two servers running, each with an own mysql server for the accounting records. If server 1 fails server 2 takes over. The accounting data is exchange with radrelay, I'm thinking to switch from this fail-over concept to a load-ba
