SSL VPN Network Access
SSL VPN lets remote users use their web browsers for a very easy-to-use VPN solution. A user just browses
to the Zyxel Device's web address and enters his user name and password to securely connect to the
Zyxel Device's network. Here full tunnel mode creates a virtual connection for a remote user and gives
him a private IP address in the same subnet as the local network so he can access network resources in
the same way as if he were part of the internal network.

User-Aware Access Control
Set up security policies to restrict access to sensitive information and shared resources based on the user
who is trying to access it. In the following figure user A can access both the Internet and an internal file
server. User B has a lower level of access and can only access the Internet. User C is not even logged in,
so and cannot access either the Internet or the file server.
