VPN Tunnel Secret
This value sets the attribute number for the VPN tunnel secret. The tunnel 
secret is a shared secret between the VPN Client and the RADIUS server 
which is used for authentication of tunnel connections. This attribute number 
must also be set up in the RADIUS server’s dictionary file. The value may 
range between 64 and 191. The default is 69.
VPN Group Info
This value sets the attribute number for the VPN group configuration. The 
group configuration defines tunneling profiles for a group of one or more 
VPN Client users. This attribute number must also be set up in the RADIUS 
server’s dictionary file. The value may range between 64 and 191. The default 
is 77.
VPN Authentication
This set of radio buttons sets the authentication protocol to be used for vali-
dation of remote VPN Client users to the RADIUS server. 
If Use CHAP is selected, CHAP will be used to validate remote VPN 
Client users to the RADIUS server. 
If Use PAP is selected, PAP will be used to validate remote VPN Client 
users to the RADIUS server. This should only be used for an older 
RADIUS server which does not support CHAP authentication.
PAP Authentication Secret
This is the secret used to authenticate and encrypt packets before they are 
passed on to the RADIUS server. The PAP authentication secret can be a 
string from 1 to 255 ASCII characters in length.
>
Primary Server IP Address
The device will attempt to contact this RADIUS server first when it needs to 
exchange RADIUS information. The address should be entered in 
dotted-decimal notation (e.g. 198.238.41.7).
>
Primary Server Retries
The device will try to resend a packet if the primary RADIUS server doesn’t 
acknowledge it within a timeout period. The timeout period for packets 1 
through 10 is (in seconds): 1, 1, 2, 2, 3, 3, 4, 4, 5, 5.
If the retry limit is reached and a secondary server is configured, the device 
will attempt to communicate with the secondary server.
Possible values range between 1 and 10 with a default of 5.
