Hi I'm working on an in-place rebuild of another radius product using 3.0.10 and noticed something very stupid that an upstream NAS is doing. It's going to be a major challenge to get the upstream NAS corrected. It's sending Auth & Acct messages on 1646. I tried setting the type to auth+acct in the sites-enabled/default listen section: listen { ipaddr = * port = 1646 type = auth+acct # interface = eth0 # clients = per_socket_clients But if I receive an accounting message on that port, it gets rejected: Listening on auth+acct address * port 1646 bound to server default Ready to process requests Receive - Invalid packet code 4 sent to authentication port from client Mobile port 50016 Ready to process requests If I swap it back to acct then the Auth messages get rejected. Any ideas on how to sort this?
