Hi, Just experienced a bit of strange behaviour, or at least seems strange to me. One of our FR 2.1.7 boxes has been proxying access-requests with a source port of 1815, to which the authenticating server has replied to with an access-accept on port 1815, only there is no listener for port 1815 running on the box and hence fails. This was happening to ~50% of requests, but once one failed the FR box was marking the authenticator dead. It started yesterday following a FR restart for a small config change (added a client to client.conf), I restarted it about an hour ago and it seems to be behaving now. Is that as odd as it seems, or am I missing something? Thanks, Jezz. ------------------------------------- Jezz Palmer Library & Information Services Swansea University Singleton Park Swansea SA2 8PP -------------------------------------
