I do not recommend this, as it allows for a trivial DOS on your RADIUS
server. Are the NASes making the request, or a proxy server?
There are two registry settings:
that can do what you want. Set IPCheck to 0, and GlobalSecret to
whatever the secret is. If RadiusNT can't find the IP Address in
its list and the above is set to 0, then it will accept the request
and use the Global Secret.
Note: If you enable this, someone knowing your RADIUS server IP
address could simply use radlogin to create a DOS attack. Therefore,
think carefully before enabling it.
