Hi, I've noticed that on our radius server logs lots of "EAP state variable not found", after some packet dump analysis (also -Xf) I've noticed that one of the cases that this happened was when some EAP Identity packets are duplicated during parallel authentications (I mean, when at least one session already began from the same client, and we're receiving duplicate ). I've noticed that these duplicate packets come with just a little difference which is the Proxy-State, the duplicate packets then, in my opinion could be caused by some bad proxying implementation (client EAP Identity passing through 2 or more proxies?), or even bad load balancing. Also, we did an upgrade of one of the two proxies connected to our home radius server and somehow noticed that the amount of EAP state errors was lower in the old version (1.1.7) than in the newer (2.1.3) (although its hard to confirm that). I've tried to compare the code from 1.1.7 and 2.1.3 and didn't come to a clear conclusion if its there any special treatment to duplicate proxied packets between 1.1.7 and 2.1.3 (while proxying). Thanks for your time. Jean F. Mousinho
