•Use the VPN > SSL VPN > Access Privilege screens (see Section 21.2 on page 318) to
configure SSL access policies.
• Use the Click VPN > SSL VPN > Global Setting screen (see Section 21.3 on page 322) to set
the IP address of the ZyWALL (or a gateway device) on your network for full tunnel mode access,
enter access messages or upload a custom logo to be displayed on the remote user screen.
21.1.2 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.

An SSL access policy allows the ZyWALL to perform the following tasks:
• limit user access to specific applications or file sharing server on the network.
• allow user access to specific networks.
• assign private IP addresses and provide DNS/WINS server information to remote users to access
internal networks.
