Thank you Brian,
I know it is possible. My concern is HOW TO DO IT. That's what I need help with.  Can you help?

I run 5 instances of FR 2.x and two of 3.x on the same box in production with no problems,
mainly to reduce the potential impact of administrative changes and upgrades.  There are
plenty of configuration directives to separate sockets and logging and whatnot.  The
configuration file can be specified on the command-line and you can even override where the
dictionary comes from if needed.

Though they are deprecated, there are older RADIUS ports at 1645/1646 that might be better
supported if you stumble across a crummy NAS.

Subject: How to run multiple instance of freeRADIUS on one server

Hello, I am using freeRADIUS 2.0 on Ubuntu Server 12.04 LTS

I want to know how to run  multiple instances of freeRADIUS on one server.
In this case I want instance-A to have the authentication port to be 1812 and instance-B to have authentication port to be 1814.
The acct port for instance-A to be 1813 and the acct port for instance-B to be 1815.
I am thinking this is possible but I've been google for months now and have come up with nothing.  Can you please point me in the right direction?

Kind Regards,
