CHAPTER 12
SSL VPN
12.1 Overview
Use SSL VPN to allow users to use a web browser for secure remote user login. The remote users do not
need a VPN router or VPN client software.
12.1.1 What You Can Do in this Chapter
Use the VPN > SSL VPN screens (see Section 12.2 on page 185) to configure a SSL access policy.
12.1.2 What You Need to Know
Full Tunnel Mode
In full tunnel mode, a virtual connection is created for remote users with private IP addresses in the same
subnet as the local network. This allows them to access network resources in the same way as if they
were part of the internal network.
Figure 130 Network Access Mode: Full Tunnel Mode
Split Tunnel Mode
In split tunnel mode, only the traffic going to the networks behind the Zyxel Device is encrypted. Traffic
going to the Internet from the remote client does not go through the Zyxel Device and is not encrypted.
