^ - That’s easy. To complicate, I need to also authenticate real users from the same source server, using a different shared secret. (anyone can view the one above, so not secure) Ideally, I’d like to also lockdown the above secret key, to the single user.
Could you add a second IP address to the server (i.e. an alias), and bind to that when sending your test queries? I was just wondering about to reply and say exactly the same thing. On my development server I have bound 6 secondary IP addresses to it and use Packet-Src-IP-Address In the first line of the request. http://lists.freeradius.org/pipermail/freeradius-devel/2012-October/007185.h... The other option as suggested is to add multiple IP addresses on the server or a listen statement in the configuration with a new port and use a per port clients to specify the shared secret. In the end after various different ways of achieving it I created my own custom VSA and include that in the request to determine the NAS type. Then for normal NASes I use client shortname and make decisions in code. And for my development server I don't define client shortname and pass it in as an additional VSA.
