Hello, I have a functioning FreeRadius 3.0.10 installation that currently uses the rlm_sql module for accounting and authorization. The setup is composed of 2 FreeRadius servers with a MariaDB/Galara cluster. I'm interested in using the nas table in the database rather than clients.conf when configuring my clients. Each NAS "client" has a corresponding home_server defined in sites-enabled/originate-coa, which the client gets tied to with the coa_server parameter in clients.conf: [clients.conf] client hk-wlc1 { ipaddr = 10.129.3.13 secret = secret nas_type = cisco coa_server = hk-wlc1-coa } [originate-coa] home_server hk-wlc1-coa { type = coa ipaddr = 10.129.3.13 port = 1700 secret = secret coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } The provided radius schema does not include a coa_server field in the nas table. One would think that would be needed in order for clients that are defined in the db to use the appropriate CoA server. Looking at the source code, I located the function generate_sql_clients(), which appears to parse the records returned from the query defined for the particular DB platform (mods-config/sql/main/mysql/queries.conf in this case). It doesn't appear to be possible to define a coa_server for a client that is defined in the nas table. Is it possible for FreeRadius to identify the appropriate CoA home_server based on the IP address that originated the request (thus not requiring the coa_server parameter)? Bryan
