How to Configure a Generic Web Forward

  • Last updated on

Create Web Forwards to allow SSL VPN users to access web-based internal applications. There are predefined Web Forward types for Outlook Web Access and SharePoint servers as well as generic settings that allow you full control over how the web content is rewritten. Web forwards can also be customized using User Attributes. User Attributes are defined by the administrator and filled in by the end user in the mobile or desktop portal. They allow for personalized URLs or Single Sign-On for Web Forwards.
