Thank you to for you response. Certainly in the proxy.conf file we can read

So, after 20 seconds, my radiusxx Freeradius must consider it dead, and then, I think that Freeradius can proxy the request until the response_window = 50 time gone. Maybe I'm mitaked, so I would like to know how if I'm in an error. > > When a home server does not respond to an Access-Request, the proxy process > has failed and the default behavior is to reject the users Access-Request. > The proxy server marks the home server as a zombie and after another 40 > seconds has passed, the proxy server marks the home server as dead.
