(RADIATOR) IP Lease problem

[Hugh Irvine]

Hello Skeeve -

I think I would be inclined to use IP address pool(s) on the NAS(s) for 
these cases and let the NAS do the address management.

It is certainly true that lost stop records will cause lots of problems.

And yes, it is complicated, in no small part due to the well known 
limitiations of the radius protocol itself.

regards

Hugh
