The Novell® SSL VPN can be deployed as either an ESP-enabled SSL VPN or a Traditional SSL VPN.
When SSL VPN is deployed without the Access Gateway, an Embedded Service Provider (ESP) component is installed along with the SSL VPN server. This deployment requires the Identity Server and the Administration server to also be installed. This type of deployment is called an ESP-enabled Novell SSL VPN.
When SSL VPN is deployed with the Access Gateway, it is called a Traditional Novell SSL VPN. In this type of installation, SSL VPN is deployed with the Identity Server, Administration Console, and the Linux Access Gateway components of Novell Access Manager.
