I am on Freeradius 3.0.15 When i add my client (NAS IP) in clients.conf my configuration of the CoA is perfect, working fine without any problem. The issue is my clients list should come from the database but not this file. I add the client in my nas table and during the server startup i see the message rlm_sql (sql): Executing select query: SELECT id, nasname, shortname, type, secret, server FROM nas rlm_sql (sql): Adding client 192.168.0.12 (myNAS) to global clients list rlm_sql (192.168.0.12): Client "myNAS" (sql) added But when I send a CoA request i get the message WARNING: Unknown destination 192.168.0.12:3799 for CoA request. I am looking for a solution where i can have clients listed only in database but not in the clients.conf file. Any thoughts?? Thanks.
