see 

Select one of the following radio buttons to specify whether or not Extended 
Authentication (XAUTH) is enabled, and–if enabled–which device is used to 
verify user account information:
• None. XAUTH is disabled. This the default setting.
• Edge Device. The UTM functions as a VPN concentrator on which one or 

more gateway tunnels terminate. The authentication mode that is available 
for this configuration is User Database, RADIUS PAP, or RADIUS CHAP.

• IPSec Host. The UTM functions as a VPN client of the remote gateway. In 

this configuration the UTM is authenticated by a remote gateway with a user 
name and password combination.

Authentication 
Type

For an Edge Device configuration: from the pull-down 
menu, select one of the following authentication types:
• User Database. XAUTH occurs through the UTM’s user 

database. Users must be added through the Add User 
screen (see 

).

• Radius PAP. XAUTH occurs through RADIUS Password 

Authentication Protocol (PAP). The local user database is 
first checked. If the user account is not present in the 
local user database, the UTM25 connects to a RADIUS 
server. For more information, see 

.

• Radius CHAP. XAUTH occurs through RADIUS 

Challenge Handshake Authentication Protocol (CHAP).
