VPN Settings
The SSL VPN settings page, found at VPN > SSL > Settings, has been reorganized to be more intuitive. The settings are now found in the following sections:
Connection Settings define how users connect and interact with an SSL VPN portal. This section includes Listen on Interface(s), Idle Logout, and Server Certificate.
Tunnel Mode Client Settings define the settings that clients will receive upon connecting to the VPN. This section includes Address Range and Allow Endpoint Registration.
Authentication/Portal Mapping allows you to define different portals to different users and groups.
