SSL VPN
26.1  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.

) to configure SSL access policies. 
• Use  the  Click  VPN > SSL VPN > Global Setting screen (see 
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

26.1.2  What You Need to Know
There are two SSL VPN network access modes: reverse proxy and full tunnel. 
Reverse Proxy Mode
In reverse proxy mode, the ZyWALL is a proxy that acts on behalf of the local 
network servers (such as your web and mail servers). As the final destination, the 
ZyWALL appears to be the server to remote users. This provides an added layer of 
protection for your internal servers. 
With reverse proxy mode, remote users can easily access any web-based 
applications on the local network by clicking on links or entering the provided URL.
