When there's no NAS-Port in rad_request... the server doesn't assign an IP address; That's why in my opinion there's no Framed-IP-Address in Access-Accept message. If my reasoning is correct, I'd like to highlight that NAS-Port is not a mandatory attribute when it comes to Mobile telephony environment. Is there any workaround once again to bypass this. I can suggest one..i.e to update the Access-Request using unlang and hope it would work. auth: type Local auth: user supplied User-Password matches local User-Password Login OK: [test/test] (from client SSS port 0 cli 44444444488) +- entering group post-auth rlm_sqlippool: unknown NAS-Port ++[sqlippool] returns noop } # server example Sending Access-Accept of id 56 to 192.168.1.4 port 1812 Primary-DNS-Server = 192.168.2.2 Secondary-DNS-Server = 192.168.2.2 Proxy-State = 0x30303338 Finished request 0.
