Thanks Simon for replying back.
Well, we have had this radius box for quite some time now, running 
perfectly and does it's little job.  I think it has an uptime of almost 
three years now.  Upgrading would just mean more downtime, figuring out 
new kinks.  The whole thing came up cause we have to now give access to 
another set of users at a remote site.  But if we have to upgrade then I 
guess we will do it.  We were just trying to figure out a quick and easy 
fix, and I'm sure that there are solutions out there.
