2.2.2 SSL VPN Network Access
You can configure the ZyWALL to provide SSL VPN network access to remote
users. There are two SSL VPN network access modes: reverse proxy and full
tunnel.
2.2.2.1 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.
