Hi All, we have a problem with some Radius Client that, cause of malfunction, sometimes re-send a specific stop RADIUS messages several times, it just change the stop time but all the other attribute and data are the same (so it easy to find it). We use freeradius v.2 as proxy so all these messages pass through it, and we'd like that freeradius forwards to the Main RADIUS server just the first one. Is it possible and how?
