link that displays an authentication page. If authentication is successful, the VPN tunnel has
been established.
To enable SUA, you use the following command on the Easy VPN Server:
vpngroup groupname secure-unit-authentication
groupname is the alphanumeric identifier for the VPN group for which you want to
enable SUA.
After the tunnel is established, other users on the remote network (protected by the Easy
VPN Remote device) can access the network protected by the Easy VPN Server without
further authentication. If you want to control access by individual users, you need to
implement Individual User Authentication (IUA). IUA is explained in the next section.
