Hello all,

                I am running FreeRadius 2.1.8 with two NAS clients and a couple of end devices being authenticated successfully with EAP-TTLS. My setup was running just fine on IPv4 and I would like to jump to IPv6. My first trial seems ok, but not ideal, so here are my IPv6 related questions :

a) Why am I seeing in my radius –X output lines as the following :

++[detail] returns ok

[unix] IPv6 is not supported!

++[unix] returns noop

rlm_radutmp: IPv6 not supported!

++[radutmp] returns noop

What could trigger that “IPv6 is not supported” output? Is there something that might be going wrong, because clients get authenticated successfully as far as I can tell but I am afraid that something else might be broken.

b) My FreeRadius machine has “an easy to remember” IPv6 address e.g. 2001:a::1 and NAS clients are using this to send packets to FR. However it seems that FR is configuring another IPv6 address from the router advertisements that it gets from the access network. The problem is that when this happens FR replies to NAS with packets coming from the autoconfigured address as source and thus breaks the setup as NAS are waiting packets from 2001:a::1. Is there a way to force FR to generate packets coming from the manually configured IP (2001:a::1) ?

c) Is there a plan to get a dual stack FreeRadius? It would be really advantageous to be able to run FreeRadius in both ipv4 and ipv6 at the same time.

Thanks a lot in advance,

Panos
