10. Using RADIUS
•
What is RADIUS?
A Network Access Server (NAS, e.g., a Router) operates as a client of RADIUS.
The RADIUS client is responsible for passing user information to designated
RADIUS servers, and then acting on the response which is returned. RADIUS
servers are responsible for receiving user connection requests, authenticating
the user, and then returning all configuration information necessary for the client
to deliver service to the user.
Transactions between the client and RADIUS server are authenticated through
the use of a shared secret, which is never sent over the network. In addition, any
user passwords are sent encrypted between the client and RADIUS server, to
eliminate the possibility that someone snooping on an unsecured network could
determine a user's password.
There has been some confusion in the assignment of port numbers for this
protocol. The early deployment of RADIUS was done using the erroneously
chosen port number
1645
, which conflicts with the "datametrics" service. The
officially assigned port number for RADIUS is
1812
. So, be sure which port your
RADIUS server uses before configuring it in the P-202H Plus v2.
[Note]: The P-202H Plus v2 is configured with default port 1645, please reboot
the P-202H Plus v2 it is changed to 1812.

RADIUS Server Setup
1. Get Radius application S/W and install it first.
2. If the callback feature is required, please add the following ZyXEL
proprietary attributes in the
'Dictionary'
file which generally locates in the
Radius installation folder. Please note, when editing RADIUS files some
RADIUS servers do not suggest DOS Editor or Notepad. So, you can try
Wordpad instead.
