Quick IPv6 related questions

[Panagiotis Georgopoulos]

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
