NAS-IP vs srcIP

Hi everyone -
Can anyone think of a reason why the NAS-IP and the scr-IP of the access-req
packet should not be the same?

If the NAS-IP is configurable in the NAS, then the NAS-IP can be set to the
IP address other than the src-ip of the NAS that is used in reqular
FreeRadius accounting/authorization packets. The source IP address of the
NAS is normally the native interface address from which access-req was sent
(but it can be configurable).

The NAS-IP would be used to address NAS in CoA requests sent from the
FreeRadius. We need this behavior to address certain deployment
requirements.



for example:

IP prot:
   srcIP: 1.1.1.1   dstIP: 2.2.2.2
Radius prot:
   code: access-request (1)
   AVPs:
        NAS-IP-Address:  3.3.3.3


scrIP != NAS-IP-Address

Thanks,
Marlon
