Hello, we are working on the FreeRadiusServer 2.1.4 + Postgresql 8.4.2, and trying to authenticate different 'users' according to the NAS-Port in the request packets. We build the db table 'nas' by the scripts nas.sql: /* * Table structure for table 'nas' */ CREATE TABLE nas ( id SERIAL PRIMARY KEY, nasname VARCHAR(128) NOT NULL, shortname VARCHAR(32) NOT NULL, type VARCHAR(30) NOT NULL DEFAULT 'other', ports int4, secret VARCHAR(60) NOT NULL, server VARCHAR(64), community VARCHAR(50), description VARCHAR(200) ); Since the 'ports' column exists in the table 'nas', we wonder if it has some relationship with the NAS-Port in the request packets. We tried some values for the column, but didn't work. Anyone can tell me the meaning of the column 'ports'? Now we can configure a virtual server for each NAS (by the column 'server' of the table 'nas'). Can I configure a virtual server for each NAS-Port? If so, how can I acheive that? Thank you!
