(RADIATOR) Dynamic Address Allocation Approaches

[Hugh Irvine]

Hello Dean -

I don't really have enough information about your environment to say  
very much, but I always find it extremely useful to have a good DBA  
involved.

In general, IP address pools on your NAS equipment are the fastest  
and most reliable, with SQL next and DHCP last.

We are available on a contract basis for consulting and design  
services as required..

regards

Hugh

NB:

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive (www.open.com.au/archives/ 
radiator)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
Have you checked the RadiusExpert wiki:
