Security Authentication Protocol
The authentication protocol is the minimum security level that the target
router must use when communicating with the remote router. This
protocol level is checked during security negotiation. The Router will
always attempt to negotiate CHAP, the highest level of security possible.
The router will not accept a negotiated security level less than the
minimum authentication level selected.
⇒
Click CHAP , PAP , or None . PAP is the default.
Note: The authentication process occurs regardless of whether a remote
router has dialed in or the target router is dialing out, and even if the
remote end does not request authentication. Authentication is a bi-
directional process, where each end can authenticate the other using the
protocol of its choice (provided the other end supports it). The parameter
in the remote router database is the minimum security level used by the
target router when challenging or authenticating the remote router.
Disable Authentication
⇒
Check the Disable Authentication box if you wish to prevent your
router from authenticating the remote router when dialing out.
The router will not request any authentication information from the
remote router, but will still reply to any PAP or CHAP authentication
request performed by the remote, such as your ISP. When this setting is
in effect, the selected remote will not be able to dial into your router since
the router always requires authentication when accepting incoming calls.
Security Authentication Password
This password is the remote router’s password used by the target router
to authenticate the remote router.
⇒
To enter or change the remote router’s password, click Remote’s
Password .
⇒
In the next window, enter a new password in the fields provided.
The password is not displayed as you enter it and must be entered
twice. A new password overrides the previous one set. Blank
passwords are not acceptable.
⇒
Click OK to set the password. Click OK again to save the security
specification.
