[How to use Listen directive in inner tunnel virtual server]

[Thomas Fagart]

Hello,

We're using freeradius 2.1.6 as a proxy server.

It receives authentication/accounting from Wimax NAS/ASN Gateway, 
(EAP/TTLS), send it to inner tunnel, and then proxy to customer home 
server.

The server where it is located has two IP interfaces and even worse on 
one of the interface we're using IP aliasing :-)

I've notice that freeradius always use the same IP to proxy from inner 
tunnel.

I know that I could use the listen directive in radiusd.conf (and 
that's what I've done) to force freeradius to choose the correct IP to 
proxy.

But this does not seems to work for inner-tunnel proxyfication.

Do you have any ideas how I could do that ( e g use two differents 
sources IP to do the proxification).

Thanks

Thomas
