Hi, Thanks for reply.
Depends.
One of the following should be applicable (1) If the NAS is different (i.e. each VLAN has its own NAS), you can take a look at raddb/sites-available/dynamic-clients. Basically it can choose a virtual server based on Packet-Src-IP-Address attribute (i.e. the NAS IP as seen by FR)
Same NAS for all VLAN
(2) If the request is plain PAP/MSCHAP, you should be able to tell the default virtual server to proxy it to another virtual server using unlang and Proxy-To-Realm It is. (EAP/TTLS with PAP) I can't see what you mean here. (3) use the same virtual server, but do selective processing (with unlang) based on some attributes that the NAS sends. e.g. if an attribute has value A, call module sql1, while if the value is B, call module sql2. This is a way but i'd like to use 2 differents config (config should change in futur for each vlan)
