whether users are legal VPN users. After passing the authentication, 
communication between VPN users and LNS users can be created. Otherwise, 
L2TP will be notified to clear the L2TP link.

Regarding user ID authentication on LNS side, usernames are in the following two 
kinds of forms:

■

Username is VPN full username, and password is VPN user registered password

■

Username is “username+domain name”, and password is VPN user registered 
password

These configurations are optional on LNS side.

Perform the following configuration in system view.

Perform the following configuration in virtual template view.

By default, local username and password are not configured on LNS side.

Tunnel clearing process occurs when there is no user, or there is failure in network 
or the administrator disconnect the tunnel on his own initiative. Either LAC side or 
LNS side can send request for clearing tunnel initiatively. The side receiving clearing 
request must send acknowledgement (ACK) information, and wait for a certain 
period of time before clearing tunnel, so as to ensure resent clearing request from 
the peer end can be correctly received in case that ACK information is lost. After 
disconnecting tunnel compulsorily, all control connection and session connection 
in the tunnel will also be cleared. After the tunnel is disconnected, it can be 
recreated when new users dial up.

These configurations are optional on LNS side.

Perform the following in the User View.
