Re: [Help-gnu-radius] GNU Radius and 'NAS has wrong ID' problem

[Paul Cole]

Hi Lambert,

Yes, the Cisco has a conf like that. Where it is sending accounting to the
radius correctly.

With my two tested users, they can both connect through the cisco PPPoE
server and authenticate with radius but the radius seems to record only one
connection (when issuing the radwho command, I see only one user connected
at a time...) and the radius log shows the message of 'NAS has wrong ID..'.

I've seen many posts about this issue and some of them are suggesting to fix
the NAS so it will send same set of information when users connect and
disconnect...but none of them is actually suggesting how...
