This is not really a cut-and-paste sort of configuration. different
cisco devices can have different config. Sometimes this is all done on
1 line, but generally this is what it looks like:
aaa server radius dynamic-author
client 1.1.1.1
client 1.1.1.2
client 1.1.1.3
client 1.1.1.4
server-key 7 12464C5F030316
auth-type any
!
The clients being the ip address from where you need to accept
connections ie. from radpwtst.
Also keep in mind, this enables the POD server on the nas, but it
doesn't necessarily listen on the ip address that you use for radius or
to connect to the device. I work on devices that have many ips and the
POD service seems to only sit on some, possible just one of the nas's ips.
