We suggest you accept the default values where available. To configure these parameters for a RADIUS
(Remote Authentication Dial-In User Service) authentication server, follow these steps:
Step 1 In the Authentication Server field, enter the hostname or IP address of the external RADIUS server. If
you configured a DNS server, you can enter a hostname (maximum 32 characters); otherwise, enter an
IP address.
Step 2 In the Server Port field, enter the UDP port number by which you access the server. Enter 0 to have the
system supply the default port number, 1645.
Step 3 In the Timeout field, enter the time in seconds to wait after sending a query to the server and receiving
no response, before trying again. Minimum is 1 second, default is 4 seconds, maximum is 30 seconds.
Step 4 In the Retries field, enter the number of times to retry sending a query to the server after the timeout
period. If there is still no response after this number of retries, the VPN Concentrator declares this server
inoperative. Minimum is 0, default is 2, maximum is 10 retries.
Step 5 In the Server Secret field, enter the RADIUS server secret (also called the shared secret); for example,
C8z077f. The maximum is 64 characters. The field shows only asterisks.
Step 6 In the Verify field, re-enter the RADIUS server secret to verify it. The field shows only asterisks.
Step 7 Click Continue to proceed.
If you selected the IPSec tunneling protocol, skip to the section Configuring the IPSec Group, page 3-18.
Otherwise, skip to the section Changing Admin Password, page 3-21.
