I only have experience with FreeRadius (version 1.1.3) which appears to
ignore the NAS-IP-Address attribute and looks only at the source address
of the incoming packet when verifying the shared secret.

I guess it would be trivial to add a bind_ip_addr option alongside
own_ip_addr. It seems very redundant to me though...

Would you like me to prepare a patch using bind_ip_addr?
